We can estimate the physical density of any material based on the unit cell, the known size of the atoms it encompasses, and their atomic mass. Since density=mass/volume, for the mass in the unit cell we simply need to determine the number of atoms per cell * their mass from the periodic table / Avogadro’s number. For the volume of the unit cell, we just need to determine the lattice parameter of the unit cell (a) following the same rules...
