if one gram of sulphur dioxide contains x molecules what will be the number of molecules in 1g of methane

Answers

Answer 1

The ratio of molecules in sulphur dioxide and methane will be the same as the ratio of their moles. So, first of all we should find out the number of moles of sulphur dioxide in 1 gram of sulphur dioxide in 1 gram of sulphur dioxide, and the number of moles of methane in 1 gram of methane. This can be done as follows :

(i) The molecular formula of sulphur dioxide is [tex]SO_{2}[/tex]

So, [tex]1[/tex]  mole of [tex]SO_{2}[/tex] = [tex]Mass[/tex] [tex]of[/tex] [tex]2'O'[/tex]

[tex]=32+2*16[/tex]

[tex]= 64[/tex] grams

Now, [tex]64g[/tex] of sulphur dioxide [tex]= 1[/tex] mole

So, [tex]1g[/tex] of sulphur dioxide = [tex]\frac{1}{64}[/tex] mole

Thus, we have [tex]\frac{1}{64}[/tex] mole of sulphur dioxide and it contains molecules in it. Now, since equal moles of all the substance contain equal number of molecules, therefore, [tex]\frac{1}{64}[/tex] mole of methane will also contain x molecules of methane.

(ii) Molecular formula of methan is [tex]CH_{4}[/tex]

So, 1 mole of [tex]CH_{4}[/tex]  = Mass of C + Mass of 4 H

[tex]=12+4*12[/tex]

Now, 16g of methane = 1 mole

So, 1 g of mathane = [tex]\frac{1}{16}[/tex] mole

We know that:

[tex]\frac{1}{64}[/tex] mole of methane contains = x molecules

So, [tex]\frac{1}{16}[/tex]  mole of contains will contain =[tex]\frac{x*64}{16}[/tex] molecules

=[tex]4x[/tex] molecules

How many grams of NaOH is needed to neutralize 90 mL of 1.5 N HCl?

Answers

mol = conc × v

= 1.5 × 0.09

= 0.135 moles of HCl

HCl + NaOH > NaCl + H2O

1 mole HCl = 1 mole NaOH

0.135 mol HCl = x

x = 0.135 mol NaOH

mass = mol × molar mass

= 0.135 × 40

= 5.4 g

NaOH = 23 + 16 + 1 = 40 g/mol

What is the required mass to prepare a 0.5M potassium chloride solution using 250mL of water

Answers

Molarity - It is defined as number of moles of solute in the given solution.

Molarity = number of moles / Volume of solution

moles = mass / molecular weight

Molecular weight of KCl =( K-39) + (Cl -35.5) = 74.5 g/mole

Volume of soultion = 250 mL = 0.25L

Molarity = 0.5 M

Now ,

Molarity = number of moles / volume of solution

= Mass of KCl / molecular weight of KCl × Volume

0.5 = Mass of KCl / 74.5 × 0.25

Mass of KCl = 0.5 × 74.5 × 0.25 = 9.3125 grams

Hence the mass of KCl required is 9.3125 grams.

The probability density function is nonnegative everywhere, and its integral over the entire space is equal to the terms "probability distribution function" and "probability function" .

What is probability density function?

In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be equal to that sample.

Probability density is the probability per unit length, in other words, while the absolute likelihood for a continuous random variable to take on any particular value is 0 (since there is an infinite set of possible values to begin with), the value of the PDF at two different samples can be used to infer, in any particular draw of the random variable, how much more likely it is that the random variable would be close to one sample compared to the other sample.

help!!!! the relative formula mass (Mr) of sodium fluoride is 42. Use the correct answer frim the box to complete the sentence.​

Answers

Answer:

mole

Explanation:

Since Sodium Chloride is ionic, it cannot be considered a molecule as per the definition of a molecule requires each of its components to be bonded together.

The formula mass of a compound is the mass of its one molecule. Since molecule is the basic unit of a compound. Thus, the relative formula mass in grams is the mass of one molecule.

What is sodium fluoride?

Sodium fluoride is an ionic compound formed by the combination of sodium and fluorine by loss of one electron from sodium to fluorine. The  formula mass of fluorine is calculated from the atomic masses of sodium and fluorine.

Atomic mass of fluorine is 19 g/mol and mass of sodium is 23 g/mol. Here only one sodium and one fluorine is present. Hence the formula mass is 23+ 19 = 42.

This is the mass of one unit of NaF. Thus mass of one sodium fluoride molecule. Where as its molar mass may differ from the formula mass. Since the molar mass is the mass of one mole of the compound NaF. One mole of compound contains 6.02 × 10²³ molecules.

9.23 x 10^23 Au atoms= moles Au

Answers

Answer:

1.533 moles Au

Explanation:

To find the moles from atoms, you just use Avogadro's number (6.02214076×10^23 mol^-1) and divide by it. Hope this helped!

Answer:

[tex]\boxed {\boxed {\sf 1.53 \ mol \ Au}}[/tex]

Explanation:

We are asked to find how many moles of gold are in 9.23 *10²³ atoms of gold.

Avogadro's Number or 6.022 *10²³ is used to convert atoms to moles. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this case, the particles are atoms of gold.

We convert using dimensional analysis. Set up a conversion factor using Avogadro's Number.

[tex]\frac {6.022 \times 10^{23} \ atoms \ Au}{ 1 \ mol \ Au}[/tex]

We are converting 9.23 * 10²³ atoms of gold to moles, so we multiply by this value.

[tex]9.23 \times 10^{23} \ atoms \ Au *\frac {6.022 \times 10^{23} \ atoms \ Au}{ 1 \ mol \ Au}[/tex]

Flip the conversion factor so the units of atoms of gold cancel.

[tex]9.23 \times 10^{23} \ atoms \ Au *\frac { 1 \ mol \ Au}{6.022 \times 10^{23} \ atoms \ Au}[/tex]

[tex]9.23 \times 10^{23} *\frac { 1 \ mol \ Au}{6.022 \times 10^{23}}[/tex]

[tex]\frac {9.23 \times 10^{23} }{6.022 \times 10^{23} } \ mol \ Au[/tex]

[tex]1.53271338426 \ mol \ Au[/tex]

The original measurement of atoms has 3 significant figures, so our answer must have the same. For the number we found, that is the hundredth place. The 2 in the thousandth place tells us to leave the 3.

[tex]1.53 \ mol \ Au[/tex]

9.23 *10²³ atoms of gold is equal to approximately 1.53 moles of gold.

Explanation:

Pls Cross Check It, If It Correct

109.5° and it’s a Tetrahedral shape - a Carbon atom has 4 valence electrons and can share each electron with each of the 2 H atoms and 2 of the F atoms in order for them to form a full valence shell. This forms a 109.5° bond angle between F-C-F and all other atoms as the molecule experiences repulsion (atoms are trying to be as far apart as possible).

If 3.31 moles of argon gas occupies a volume of 100 L what volume does 13.15 moles of argon occupy under the same temperature and pressure

Answers

Answer:

397 L

Explanation:

Recall the ideal gas law:

[tex]\displaystyle PV = nRT[/tex]

If temperature and pressure stays constant, we can rearrange all constant variables onto one side of the equation:

[tex]\displaystyle \frac{P}{RT} = \frac{n}{V}[/tex]

The left-hand side is simply some constant. Hence, we can write that:

[tex]\displaystyle \frac{n_1}{V_1} = \frac{n_2}{V_2}[/tex]

Substitute in known values:

[tex]\displaystyle \frac{(3.31 \text{ mol})}{(100 \text{ L})} = \frac{(13.15\text{ mol })}{V_2}[/tex]

Solving for V₂ yields:

[tex]\displaystyle V_2 = \frac{(100 \text{ L})(13.15)}{3.31} = 397 \text{ L}[/tex]

In conclusion, 13.15 moles of argon will occupy 397* L under the same temperature and pressure.

(Assuming 100 L has three significant figures.)
