One mole crystal of a metal halide of the type MX with molecular weight 119g having face centered cubic structure with unit cell length 6.58 was recrystallized. The density of the recrystallized crystal was found to be2.44gcm-3. The type of defect introduced during the recrystalization may be

Options:

Answer:
B
Solution:

Calculated densityd=Z×moler massNa×volume=2.78 gcm-3
Is greater then actual density2.44 gcm-3therefore density decreases and defect is Schottky defect
