Dry Density

Dear Dr. Haddadian,  If you have the crystal structure and have the unit
cell, one can calculate the density of the crystal (perhaps not really dry!).
If it is molar volume you are interested in--you can calculate that
using Traube's rule from the formula for some types of compounds (organic
mostly).  Emory
