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

A

Ni

B

N/2

C

2N

D

4N

Text Solution

Verified by Experts

The correct Answer is:
A
one unit cell of FCC contains 4 atoms
1 atom is present in 1/4 unit cells
`2.4 xx 10^24` atoms are present in
` 2.4 xx 10^24 xx 1/4 = 6 xx 10^23 = N`
