we have density of the fcc=z*M/a^3*Na z=no of atom fro fcc it is 4 M= molecular mass Na=avagadro number a=edge length for face centered cubic unit cell=sqrt2 *a=4r,r=1.414*4.077/4=1.44*10^-8m we have density=4*108/6.022*10^23*(4.077*10^-8)^3 =1.05*10^5g/cm^3

I think in the length of the unit cell you should have edge length=4.077A0
