(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A house has a volume of 840 m^3.

What is the total mass of air inside the house at 20 degrees celcius? Assume that the pressure is 1.00 atm.

2. Relevant equations

Charles law Volume is directly proportional to Temperature

1 mol of gas at 0 degrees celcius has V = 22.4L

3. The attempt at a solution

using charles law i determined that the new volume at 20 degrees celcius would be = (20*22.4 L ) or (22.4 *10^-3 m^3)*(2) = .448 m^3

number of moles = 840 m^3 / .448 m^3 = 1875 mol

1 mol of air has a mass of about 29 g = .029 kg

so m= (1875 mol) (.029kg/mol) = 54.37 kg

my method apparenlt is faulty because the answer is rejected

Please help me solve this
