Calculate the mass in grams of 4.21×1024
molecules of propylamine. The chemical formula for propylamine is C3H9N.

Answers

Answer:

413.9 grams.

Explanation:

First, we need to calculate the molar mass of propylamine (C3H9N):

Molar mass of propylamine = (3 × atomic mass of carbon) + (9 × atomic mass of hydrogen) + atomic mass of nitrogen

Molar mass of propylamine = (3 × 12.01 g/mol) + (9 × 1.01 g/mol) + 14.01 g/mol

Molar mass of propylamine = 59.11 g/mol

Next, we can use Avogadro's number to convert the number of molecules to moles:

1 mole of propylamine = 6.022 × 10^23 molecules

moles of propylamine = (4.21 × 10^24 molecules) / (6.022 × 10^23 molecules/mol)

moles of propylamine = 7.001 mol

Finally, we can use the molar mass to convert moles to grams:

mass of propylamine = moles of propylamine × molar mass of propylamine

mass of propylamine = 7.001 mol × 59.11 g/mol

mass of propylamine = 413.9 g

Therefore, the mass of 4.21×1024 molecules of propylamine is 413.9 grams.

Gaseous methane CH4 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 2.41 g of methane is mixed with 4.6 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 2 significant digits.

Answers

Answer:

2.5 g

Explanation:

The balanced chemical equation for the reaction is:

CH4 + 2O2 → CO2 + 2H2O

From the equation, we can see that for every 1 mole of methane reacted, 2 moles of water are produced. Therefore, we need to first calculate the number of methane and oxygen moles in the reaction mixture.

The molar mass of methane is 16.04 g/mol, so the number of moles of methane present is:

2.41 g / 16.04 g/mol = 0.15 mol

The molar mass of oxygen is 32.00 g/mol, so the number of moles of oxygen present is:

4.6 g / 32.00 g/mol = 0.14 mol

We can see insufficient oxygen to react completely with all of the methane, so oxygen is the limiting reagent. To determine the maximum amount of water that can be produced, we need to use the number of moles of oxygen to calculate the number of moles of water produced and then convert that to a mass using the molar mass of water.

The balanced equation shows that 2 moles of water are produced for every 2 moles of oxygen. Therefore, the number of moles of water produced is:

0.14 mol O2 × (2 mol H2O / 2 mol O2) = 0.14 mol H2O

The molar mass of water is 18.02 g/mol, so the mass of water produced is:

0.14 mol H2O × 18.02 g/mol = 2.53 g

Rounding to 2 significant digits, the maximum mass of water that could be produced is 2.5 g.

A 32.0 L cylinder containing helium gas at a pressure of 38.5 atm is used to fill a weather balloon in order to lift equipment into the stratosphere. What is the final pressure (in atm) in the cylinder after a 355 L balloon is filled to a pressure of 1.20 atm.

Answers

Answer:

Explanation:

We can use Boyle's Law, which states that the product of pressure and volume is constant for a fixed amount of gas at a constant temperature. We can use this law to find the final pressure in the cylinder after filling the balloon.

The initial pressure and volume of the helium gas in the cylinder are:

P1 = 38.5 atm

V1 = 32.0 L

The final volume of the gas after filling the balloon is:

V2 = 355 L

Using Boyle's Law, we can write:

P1V1 = P2V2

where P2 is the final pressure in the cylinder.

Solving for P2, we get:

P2 = (P1V1) / V2

Plugging in the values, we get:

P2 = (38.5 atm x 32.0 L) / 355 L

P2 = 3.48 atm

Therefore, the final pressure in the cylinder after filling the balloon is 3.48 atm.

Temperature is a unit used to represent how hot or cold something is. It can be stated using the Celsius or Fahrenheit scales, among others. Temperature shows which way heat energy will naturally flow, i.e., from a hotter (body with a higher temperature) to a colder (body with a lower temperature) (one at a lower temperature).

What is convection currents?

By the mass motion of a fluid, such as water, air, or molten rock, convection currents move heat from one location to another. The ocean currents, atmospheric weather, and geology of the earth are all driven by the heat transfer function of convection currents.

Water boiling in a pot can be seen to have convection currents. The water is heated by the heat source at the pan's base, which also gives the water more energy and causes its molecules to flow more quickly.

urea, chemical formula (NH2)2CO, is used for fertilizer and many other things. calculate the number of N, C, O, and H atoms in 1.78*10^4g of urea.

Answers

To calculate the number of N, C, O, and H atoms in 1.78*10^4g of urea, we need to first calculate the number of moles of urea, and then use the mole ratios between the elements and the compound.

The molar mass of urea can be calculated by adding up the atomic masses of its constituent elements:

Molar mass of urea = 2(14.01 g/mol N) + 2(1.01 g/mol H) + 12.01 g/mol C + 1(16.00 g/mol O)
= 60.06 g/mol

To calculate the number of moles of urea, we can divide the given mass by the molar mass:

Number of moles of urea = 1.78*10^4 g / 60.06 g/mol
= 296.26 mol

Using the chemical formula (NH2)2CO, we can see that there are 2 nitrogen atoms (N), 1 carbon atom (C), 1 oxygen atom (O), and 2 hydrogen atoms (H) in one molecule of urea.

Therefore, in 296.26 moles of urea, there are:

- 2 nitrogen atoms x 296.26 moles = 592.52 moles of N
- 1 carbon atom x 296.26 moles = 296.26 moles of C
- 1 oxygen atom x 296.26 moles = 296.26 moles of O
- 2 hydrogen atoms x 296.26 moles = 592.52 moles of H

To convert from moles to atoms, we can use Avogadro's number, which is the number of atoms in one mole of a substance:

1 mole = 6.022 x 10^23 atoms

Therefore, in 1.78*10^4g of urea, there are:

- 2 nitrogen atoms x 296.26 moles x 6.022 x 10^23 atoms/mole = 7.16 x 10^26 atoms of N
- 1 carbon atom x 296.26 moles x 6.022 x 10^23 atoms/mole = 1.79 x 10^26 atoms of C
- 1 oxygen atom x 296.26 moles x 6.022 x 10^23 atoms/mole = 1.79 x 10^26 atoms of O
- 2 hydrogen atoms x 296.26 moles x 6.022 x 10^23 atoms/mole = 7.16 x 10^26 atoms of H

Therefore, there are approximately 7.16 x 10^26 atoms of N, 1.79 x 10^26 atoms of C, 1.79 x 10^26 atoms of O, and 7.16 x 10^26 atoms of H in 1.78*10^4g of urea.

Explanation:

40.532 g of an unknown compound X is dissolved in 351.11 mL. What is the molarity of X? Here is some information to determine the identity of X. When 1.00g of X is dissolved in water and allowed to react wtih AgNO3, all the chlorine in X precipitates and 1.95g of AgCl is collected. When 1.00g of X undergoes complete combustion, 0.900 g of CO2 and 0.735 g of H2O were collected. The empirical and molecular formula are identical. Compound X only contains carbon, hydrogen, nitrogen, and chlorine.

Answers

Firsttttt, let's use the data from the reaction with AgNO3 to determine the amount of chlorine in X:

1.95 g AgCl = (1.95 g AgCl) / (143.32 g/mol AgCl) = 0.0136 mol AgCl
0.0136 mol AgCl = 0.0136 mol Cl

Since we know the empirical formula and the molar mass of X is 40.532 g/mol, we can use the empirical formula to calculate the molecular formula. Let's assume that the empirical formula is CₐHᵦNᵧClᵹ:

From the combustion reaction, we can calculate the moles of carbon and hydrogen in X:

0.900 g CO2 = (0.900 g CO2) / (44.01 g/mol CO2) = 0.0205 mol CO2
0.735 g H2O = (0.735 g H2O) / (18.02 g/mol H2O) = 0.0408 mol H2O
0.0205 mol CO2 = 0.0205 mol C
0.0408 mol H2O = 0.0408 mol H
Using the law of conservation of mass, we can find the moles of nitrogen and chlorine in X:

0.0136 mol Cl = 0.0136 mol Clᵹ
0.0205 mol C + 0.0408 mol H + 0.0136 mol Clᵹ = 0.0754 mol total
0.0754 mol total = 0.0754 mol X

Now we can calculate the mole ratio of each element in X:

C: 0.0205 mol / 0.0754 mol = 0.272
H: 0.0408 mol / 0.0754 mol = 0.542
N: 0 / 0.0754 mol = 0
Cl: 0.0136 mol / 0.0754 mol = 0.181

The empirical formula is therefore C₀.₂₇H₀.₅₄N₀.₀Cl₀.₁₈.

The molar mass of the empirical formula is:
0.272 g/mol C + 0.542 g/mol H + 0.018 g/mol Cl = 0.832 g/mol
The molecular formula mass is 40

Answers

If Lysozyme is an enzyme that breaks bacterial cell walls. The molar mass is: 1.40×104 g/mol..

How to find the molar mass?

Osmotic pressure (Π):

Π = M × R × T

where:

M is the molarity of the solution

R is the ideal gas constant

T is the absolute temperature.

So,

M = Π / (R × T)

Π = 0.953 torr × (0.001316 atm / 1 torr) = 0.001254 atm

R = 0.0821 atm L mol-1 K-1

T = 25.0°C + 273 = 298 K

Molarity of lysozome solution = (0.001254 atm) / (0.0821 atm L mol-1 K-1 × 298 K) = 0.00005126 mol/L

Molarity of lysozome solution = 0.00005 mol/L

(0.15 g lysozome) × (1 L soln/ 0.00005126 mol lysozome) × (1 / 0.21 L soln) = 13934.56 g/mol

Molar mass of lysozome = 13934.56 g/mol

Answers

Answer:

To calculate the energy consumed by the client, we need to use the following formula:

Energy (in calories) = (grams of carbohydrate x 4) + (grams of protein x 4) + (grams of fat x 9)

First, let's calculate the amount of each nutrient in the 180ml serving:

Carbohydrates: (75 ml / serving) x (13.5 g / 75 ml) x 180 ml = 32.4 g

Protein: (75 ml / serving) x (10 g / 75 ml) x 180 ml = 24 g

Fat: (75 ml / serving) x (4 g / 75 ml) x 180 ml = 9.6 g

Now we can calculate the energy consumed:

Energy = (32.4 g x 4) + (24 g x 4) + (9.6 g x 9) = 129.6 + 96 + 86.4 = 312 calories

Therefore, the client has consumed 312 calories from the 180 ml serving of the product.

Sickle cell anemia is a genetic blood disorder that affects the shape and function of red blood cells. Hemostasis refers to process of maintaining balance between clotting and bleeding and sickle cell anemia can disrupt this balance in several ways.

One of the main effects of sickle cell anemia on hemostasis is that it can cause Vaso-occlusion, which is blockage of small blood vessels by sickle cells. This can cause tissue damage, inflammation and pain, which in turn can trigger an overactive clotting response.

Sickle cell anemia is caused by mutations in HBB gene, which provides instructions for making protein called hemoglobin.

what is Cobalt (II) iodide and sodium carbonate net ionic equation

Answers

Answer:

Co2+ + CO32- → CoCO3

Explanation:

The molecular equation for the reaction between cobalt (II) iodide and sodium carbonate is:

CoI2 + Na2CO3 → CoCO3 + 2NaI

To write the net ionic equation, we need to eliminate the spectator ions, which are the ions that appear on both the reactant and product side of the equation and do not participate in the reaction. In this case, the spectator ions are Na+ and I-.

The net ionic equation for this reaction is:

Co2+ + CO32- → CoCO3

Therefore, the net ionic equation for the reaction between cobalt (II) iodide and sodium carbonate is:

Co2+ + CO32- → CoCO3
