TRIPLE: 1.20 understand the term molar volume of a gas and use its values (24 dm3 and 24,000 cm3 ) at room temperature and pressure (rtp) in calculations.
Molar volume of a gas
One mole of any gas has a volume of 24dm³
at room temperature and pressure, this is called the molar volume of a gas.
volume of gas (in dm³) = amount x 24
If we had 3 mols of Hydrogen, the volume of the gas would be
