A body centered cubic lattice is made up of hollow spheres of B. Spheres of solid A are present in hollow spheres of B. Radius A is half of radius of B. What is the ratio of total volume of spheres of B unoccupied by A in a unit cell and volume of unit cell ?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
No. of atoms of B in unit cell = 2
Total volume of B unoccupied by A
in a unit cell = 
= 
vol. of unit cell = a 3 = 
for BCC 
= 4R
∴ ρ ratio = 
=
