unit:M3-PER-MOL
The molar volume, symbol $Vm$, is the volume occupied by one mole of a substance (chemical element or chemical compound) at a given temperature and pressure. It is equal to the molar mass (M) divided by the mass density. It has the SI unit cubic metres per mole $m3/mol$, although it is more practical to use the units cubic decimetres per mole $dm3/mol$ for gases and cubic centimetres per mole $cm3/mol$ for liquids and solids
