To find the molecular formula from the empirical formula, you need to find a multiple (x) that will give you the molar mass of the compound which in the question is 50.48 g/mol.
If CH₃Cl is the empirical formula
molar mass of empirical formula = (12 × 1) + (1 × 3) + (35.5 × 1) g/mol
= 50.5 g/mol
let x = multiple
let molecular formula = Cₓ H₂ₓ
multiple = molecular mass ÷ empirical mass
= 50.5 g/mol ÷ 50.48 g/mol
≈ 1
If molecular formula = Cₓ H₃ₓ Cl
then molecular formula = C₍₁₎ H₃₍₁₎ Cl₍₁₎
= CH₃Cl
Youve gotta multiply the percentages by the masses. Like here
(.8379)(51.94)
Answer :
Charles's Law : It is defined as the volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
Mathematically,

Boiling water bath Cool bath 1 Cool bath 2
Temperature (⁰C) 99 17 2
Temperature (K)(T) 273+99=372 273+17=290 273+2=275
Volume of water 0.0 27.0 34.0
in cool flask (mL)
Volume of water= 135.8 135.8 135.8
Air in flask (mL)
Volume of air 135.8 108.8 101.8
in cool flask (V)

The graph volume versus temperature for a gas is shown below.
It is false, because models don't help you get a better understanding of the world, they help you better understand what you are trying to get from it like a weather model, it helps us see the weather because it is a visual so people would know what type of weather is where.
