The volume of the unit cell of the crystal can be calculated as (3.6 \AA)3 = 46.656 \AA 3. The number of atoms in the unit cell can be calculated as (2.16 g/cm^{3})/(48.045 g/mol \times 6.023 \times 10^{23} mol^{-1} \times (46.656 \times 10^{-24} cm^{3})) = 1. .The atomic mass of the substance can be calculated as (2.16 g/cm^{3})/(46.656 \times 10^{-24} cm^{3}) = 48.045 g/mol.
