pyknometric density:-Pycnometric density is the closest approximation to true density calculated from the molecular weight and crystalline lattice of a substance.
First density = 2.165 * 10 ^3
Difference of density = 2178-2165 = 13 kg/m 3
Therefore,
fraction of unoccupied site = 13/2178 = 5.96 * 10 -3
