What is the volume of a sample of oxygen gas has a mass of 50 grams and is under pressure of 1.20 atm at 27 degrees celsius?

3. The attempt at a solution

Density = Pressure(in pascals)/(specific gas constant * Temperature (in kelvins))

1 atm = 101,325 pascals ~ 1.2 atm = 121,590 pascals

27^{o}Celsius = 300.15 K

Density = (121,590 pascals)/(8.314 * 300.15 K) = 48.72 kg/m^{3}= 48,720 g/m^{3}

48,720 g/m^{3}= 50 g/V ~ V = 1.03 x 10^{-3}m^{3}
