Molar volume

The molar volume is equal to the atomic weight divided by the density.

cm³

Notes

The molar volume is also known as the atomic volume.

The standard SI units are m³. Normally, however, molar volume is expressed in units of cm³. To convert quoted values to m³, divide by 1000000.

The molar volume depends upon density, phase, allotrope, and temperature. Values here are given, where possible, for the solid at 298 K.
