A body centred cubic lattice is made up of hollow sphere of B. Sphere of solid A are present in hollow sphere of B. Radius of A is half of the radius of B. What is the ratio of total volume of sphere B unoccupied by A in unit cell and volume of unit cell?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Effective number of atoms of B present in a unit cell = 2
Total volume of B unoccupied by A in a unit cell
Volume of unit cell = a 3
Ratio of total volume of sphere B unoccupied by A in unit cell and volume of unit cell =
