How is the ideal density of a substance calculated from unit cell data?
The ideal density of a general crystalline unit cell is calculated by the following method: D is the density expressed in grams per cubic centimeter (g / cm3), Z is the number of atoms or molecules per unit cell, FWT is the formula weight of the atoms or molecules expressed in grams (g), Na is Avogadro’s Number = 6.023 x 1023 atoms or molecules, and V is the volume of the unit cell expressed in cubic centimeters (cm3).
