The volume occupied by one mole of any substance is called its molar volume. It is denoted by V m . Molar volume of the substance depends on temperature and pressure. One mole of all gaseous substances at 273 K and 1 atm pressure occupies a volume equal to 22.4 litre or 22,400 mL. The unit of mola..
