Atomic mass of potassium is 39 g.
In a BCC unit cell, there are 8 atoms at the corner of
a cube and 1 atom at the centre. Number of atom per unit cell =
8x1/8+1x1=
Number of atoms in 4.0 g of potassium = 4/39 x 6.02
x10
Number of unit cells in 4.0
of potassium = 4/39 x 6.02 x 1023/2 =3.09 x 10% unit cells
