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 1

From the gas equation

pV = (W/M)RT

Where W is the mass of the gas and M is the molar mass of the gas.

For CO₂, M = 44 g/mol

1 bar x V = {8.8 g}/{44 g/mol} x 0.083 bar L k^-1 mol^-1 x 304.1 K

or, V = 5.05 L
