How can you determine the atomic mass of an unknown metal if you know its density and the dimension of its unit cell? Explain.

Let ‘a’ be the edge length of a cubic unit cell and it contains ‘Z’ atoms of a substance of atomic mass ‘M’.

From the above expression for density, d we can calculate the atomic mass, M of metal as other parameters are known.
