You understand that a mole of a substance contains the molecular weight of that substance, expressed in grams. You also understand that a mole of a particular substance contains 6.0221415 x 10^23 molecules. This number is known as Avogadro's constant and it is fundamental to chemical calculations. Molar volume is another important chemical constant. It is the volume that a mole of a particular gas occupies when at standard temperature and pressure. The molar volume of an ideal gas at STP is 22.413996 liters. This means 22.414 liters of gas at STP contains exactly 6.0221415 x 10^23 molecules. There is no "molar volume for the elements" because the term only applies to an ideal gas at standard temperature and pressure.

The molar volume is the number of moles / liter.
Vm = m / M x Eg
m - mass of the dissolved substance
M - molar mass
Eg - equivalent gram

It is the molecular weight in grams divided by the density.
It will be expressed in g/cm^3/mole
