the crystal AB(rock salt structure) has molecular weight 6.023Y, where Y is an arbitrary number in u. If the minimum distance between cation and anion is Y^1/3nm and observed density is 20kg/m^3. Find the density in kg/m^3 and the type of defect?

Density=4x6.023xy/6.023x1023x8xyx10-27
=5Kgm3
Since the density calculated is < than the density observed so it means the defect is metal excess defect.
