An elementoccurring in the bcc structure has `12.08 xx 10^(23)` unit cells .The total number of atoms of the element in these cells will be

Options

A. `24.16 xx 10^23`
B. `36.18 xx 10^23`
C. `6.04 xx 10^23`
D. `12.08 xx 10^23`

Answer

A

Explanation

There are two atoms in a bcc unit cell . So, number of atoms in `12.08 xx 10^23` unit cells
` = 2 xx 12.08 xx 10^23 = 24.16 xx 10^23` atoms .
