A metal 'M' is crystallised in F.C.C lattice. The number of unit cells in it having `2.4xx10^(-24)` atoms

A

N

B

N/2

C

2N

D

4N

Text Solution

Verified by Experts

The correct Answer is:
1
One unit cell contains 4 atoms.
1 atom is present in `(1)/(4)` unit cells
`2.4xx10^(24)` atoms are present in
`2.4xx10^(24)xx(1)/(4)=6xx10^(23)=N`
