Answer:
447.64 grams
Explanation:
To find the mass when given moles, it is a pretty simple process.
I start by finding the molar mass of chloric acid, which comes out to 84.46 grams/mol. To find the MM (molar mass), you just take the mass of each element in the molecule from the periodic table and add them all together.
After this, you set up the equation by taking the moles given and multiplying it by the molar mass. This gives you the new value in grams (since we cancelled out the moles). I have attached my work below.
I hope this helps! :^)
The mass of 5.3 moles chloric acid has been 447.85 g.
The mass of 1 mole of a compound has been equivalent to the molar mass of the compound. The molar mass of a compound has been the sum of the constituent atoms in a formula unit.
The molar mass (mwt) of chloric acid has been given as:
[tex]mwt=m_H\;+\;m_C_l\;+\;(m_O\;\times\;3)[/tex]
By substituting the values for the mass of constituent atoms, the molar mass has been given as:
[tex]mwt=1\;+\;35.5\;+\;16\;\times\;3\\mwt=36.5\;+\;48\\mwt=84.5[/tex]
The molar mass of chloric acid has been 84.5 g/mol.
The mass of 1 mole of chloric acid has been 84.5 g/mol. The mass of 5.3 moles chloric acid has been:
[tex]\rm 1\;mol=84.5\;g\\5.3\;mol=5.3\;\times\;84.5\;g\\5.3\;mol=447.85\;g[/tex]
The mass of 5.3 moles chloric acid has been 447.85 g.

Determine the wavelength of a radio station transmitting a broadcast at 520 Megahertz.
Answers
The wavelength of the radio station broadcasting at 520 megahertz is 0.58m.
HOW TO CALCULATE WAVELENGTH:
The wavelength of a wave can be calculated by dividing the speed of the wave by its frequency as follows:λ = v/f
Where;
v= velocity of the wave (3 × 10⁸m/s)f = frequency (Hz)According to this question, a radio station is transmitting a broadcast at 520 Megahertz. The wavelength is calculated as follows:λ = 3 × 10⁸ ÷ 5.2 × 10⁸λ = 0.577 × 10⁸-⁸λ = 0.58mTherefore, wavelength of the radio station broadcasting at 520 megahertz is 0.58m.Learn more at: https://brainly.com/question/19601903?referrer=searchResults

Explain the law of conservation of mass. Give an example of how mass is conserved using numbers to justify your answer.
Answers
Answer:
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction.
For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
Another example, solar panels don't create solar energy. They harness energy from the sun and transform it into another type of energy (electricity).

The role played by hydraulic fluid in a hydraulic machine is as a medium for
the transfer of force.
Hydraulic fluid is used primarily in a hydraulic machine for the transfer of
force from one point to another. This makes the system able to perform the
required functions.
Hydraulic fluid also has other functions such as being a coolant and as a
cleaning agent(removal of contaminants) which aren't its major function.

Find the volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide.
Answers
The volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide is 0.15L
The reaction of sulphuric acid and sodium hydroxide is expressed as:
[tex]2NaOH + H_2SO_4 ==> Na_2SO_4 + 2H_2O[/tex]
Determine the moles of NaOH present
Molar mass of NaOH = 23 + 16 + 1 = 40g/mole
Given that mass of NaOH is 75.0g
Mole of NaOH = 75/40 = 1.875moles
Determine the number of moles [tex]H_2SO_4[/tex] needed to react with 1.875 moles NaOH
Moles of [tex]H_2SO_4[/tex] = [tex]\frac{1.875}{2} = 0.9375moles of H_2SO_4[/tex]
Recall that volume = Molar mass * number of moles
Volume of [tex]H_2SO_4[/tex] = 0.160 * 0.9375
Volume of [tex]H_2SO_4[/tex] = 0.15L
Hence the volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide is 0.15L

Answer:Physical and chemical laboratory experiments include three primary sources of error: systematic error, random error and human error

Explanation:
The difference in temperature will be:
35 - 10 = 25
The outer duct surface is heated 25°C by the air from 10°C to 35°C;
This heat gain is simply divided by 0.2m to get heat gain per unit length:
25/0.2 = 125

What is the molarity of Ca(NO3)2 in a solution resulting from mixing 150.0 mL of 0.200 M HNO3 with 150.0 mL of 0.0100 M Ca(OH)2
Answers
The molarity of the Ca(NO3)2 solution would be 0.005 M
First, let us look at the balanced equation of the reaction:
[tex]2HNO_3+Ca(OH)_2 ---> Ca(NO_3)_2+2H_2O[/tex]
The mole ratio of HNO3 to Ca(OH)2 is 2:1.
Mole of HNO3 = molarity x volume
= 0.2 x 150/1000
= 0.03 mole
Mole of Ca(OH)2 = 0.01 x 150/1000
= 0.0015
Thus, there is no limiting or excess reactant.
Also from the equation, mole ratio of Ca(OH)2 to Ca(NO3)2 is 1:1. Hence, the mole of Ca(NO3)2 would also be 0.0015 mole.
The total volume of the resulting solution would be: 150 +150 = 300 mL
Thus, the molarity of the resulting Ca(NO3)2 would be:
Molarity = mole/volume
= 0.0015/0.3
= 0.005 M
