A compound CuCl has face - centred cubic structure. Its density is 3.4g cm^(-3) . What is the length of unit cell ?

An element with atomic mass 60 having fcc structure has a density of 6.23 "g/cm"^3 .What is the edge length of unit cell ?

Density of a unit cell is same as the density of the substance. If the density of the substance is known, number of atoms or dimensions of the unit cell can be calculated . The density of the unit cell is related to its mass(M), no. of atoms per unit cell (Z), edge length (a in cm) and Avogadro number N_A as : rho = (Z xx M)/(a^3 xx N_A) A metal X (at. mass = 60) has a body centred cubic crystal structure. The density of the metal is 4.2 g cm^(-3) . The volume of unit cell is

The compound CuCl has Zns structure. Its density is 3.4 g cm^(-3) . What is the length of the edge of the unit cell ?
