Question:

Calculate the volume occupied by 8.8 g of CO2 at 31.1°C and 1 bar pressure.

R = 0.083 bar L K–1 mol–1.

Answer:

From the gas equation,

PV = (w/M) RT

Where w is the mass of the gas, M is the molar mass of the gas

For CO2 , M = 44 g/mol

Substituting the given values ,we get

1 x V  = (8.8 / 44) x 0.083 x 304.1

 = 5.05 L

Hence, the volume occupied is 5.05 L.
