Formula and explanation
Under standard conditions (STP: 0°C, 101.325 kPa), the molar volume (Vm) of any ideal gas is approximately 22.4 L/mol. Formula: V m = (V)/(n) Applicable conditions: Ideal gas, standard conditions (STP). Explanation: Vm(STP) ≈ 22.4 L/mol. This is an important constant for relating gas volume to amount of substance.
