We know that density is related to molar mass and edge length by the formula :

                                                      Density (d)= \frac{z.M}{a^3.N_A}

                                                                       M=\frac{d.a^3.N_A}{Z}

where, d=Density
            a3 = The volume of the unit cell
            M= Atomic mass
          Z = No. of atoms in unit cell    
         Na= Avogadro’s number.
