Potassium has bcc system
Number of mole$\text{=}\text{39/39}\text{=}\text{1}$mole
$\text{1}$mole of atoms =$\text{6}\text{.022}\times {\text{10}}^{23}$atoms$\text{=}\text{N}$
$\because$In bcc system$\text{2}$atoms are present in$\text{1}$unit cell.

$\therefore \text{N}$number of atoms are present in$\frac{\text{N}}{\text{2}}$unit cells.
