One mole crystal of a metal halide of the type MX with molecular weight 119 g having face centered cubic structure with unit cell length 6.58 Å 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
