The molar volume is equal to the atomic weight divided by the
density. 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. WebElements now has an online
