Question

An element occuring in the bcc structure has 12.08 × 1023 unit cells. The total number of atoms of the element in these cells will be (A) 24.16 × 1023 (B) 36.18 × 1023 (C) 6.04 × 1023 (D) 12.08 × 1023

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

Q. An element occuring in the bcc structure has $12.08 \times 1 0^{23}$ unit cells. The total number of atoms of the element in these cells will be

$24.16 \times 1 0^{23}$

$36.18 \times 1 0^{23}$

$6.04 \times 1 0^{23}$

$12.08 \times 1 0^{23}$

There are two atoms in a bcc unit cell.
So, number of atoms in $12.08 \times 1 0^{23}$ unit cells
$= 2 \times 12.08 \times 1 0^{23} = 24.16 \times 1 0^{23}$ atoms.
