1 mole of any gas at (STP) standard temperature
(0C) and pressure (1 atm) has a volume
of 22.4 cubic decimeters (dm3), which is the
same as 22.4 liters (L). This volume of gas is
called a molar volume because it is the volume
of 1 mole of a gas at standard conditions.
To calculate molar volume of a gas: (X)
