Molar volume

Definition

The volume occupied by one mole of a gas at a stated temperature and pressure.

Used by Edexcel

Specification 5.16C, 5.17C · Paper 1

The volume occupied by one mole of a substance; for any gas at room temperature and pressure it is approximately $24\,\text{dm}^3\,\text{mol}^{-1}$ .
The molar volume is the volume occupied by one mole.
Revise: Molar Volume
The volume occupied by one mole of a gas under stated conditions. At room temperature and pressure, the value used here is $24\ \mathrm{dm^3\,mol^{-1}}$ or $24\,000\ \mathrm{cm^3\,mol^{-1}}$ .
Revise: Molar Volume Calculations
Revise: Suggested Practicals

1
Match the units before using a molar volume: use $24\,\text{dm}^3\,\text{mol}^{-1}$ with volumes in $\text{dm}^3$ , or $24\,000\,\text{cm}^3\,\text{mol}^{-1}$ with volumes in $\text{cm}^3$ .
