BRAINCAKEMolar Volume Calculation - 1
The molar volume is the volume occupied by one mole of any gas. At room temperature and pressure (r.t.p., 298 K and 101 kPa) it is 24.0 dm3 mol-1. It does not matter which gas it is: one mole of hydrogen and one mole of carbon dioxide take up the same volume at the same temperature and pressure.
This gives two linked equations:
volume of gas (dm3) = amount (mol) × 24.0
