The volume of atom present in a face-centred cubic unit cell of a metal (`r` is atomic radius ) is

A

`(20)/(3) pi r^(3)`

B

`(24)/(3) pi r^(3)`

C

`(12)/(3) pi r^(3)`

D

`(16)/(3)pi r^(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
`V=n xx ((4)/(3) pi r^(3)) =4 xx ((4)/(3) pi r^(3)) =(16)/(3) pi r^(3)`
