An element occuring in the bcc structure has 12.08 x 10²³ unit cells. The total number of atoms of the element in these cells will be

A) $24.16 \times 10^{23}$

B) $36.18\times10^{23}$

C) $6.04\times 10^{23}$

D) $12.08\times10^{23}$

Option A

There are two atoms in a bcc unitcell. So, number of atoms in 12.08 x 10²³ unit cells = 2 x 12.08 x 10²³ = 24.16 x 10²³ atoms.
