Some facts#
- Molecular volume is the volume occupied by 1 mole of substance i.e. a sample containing about atoms or molecules (→ see Avogadro number).
- The basic unit of the molar volume in the SI system is cubic meter per mole:
- The molar volume depends on temperature and pressure. The data given in this calculator refer to normal conditions i.e pressure 1013,25 hPa and temperature 0 °C.
- The molar volume of perfect gas under normal conditions is 22,415 dm3/mol.
- The volume of one mole of perfect gas is directly proportional to the temperature and inversely proportional to the pressure:
where:
- - molar volume,
- R - gas constant,
- T - temperature,
- p - pressure.
- - molar volume,
- The molar volume of real gases differs from the ideal gas value due to intermolecular interactions.
