Question

Calcium metal crystallizes in fcc lattice with edge length 556 pm. Calculate the density (in g cm-3) of metal if it contains 0.2% Schottky defects.

Solution

Correct option is

1.5427

 

Due to 0.2% Schottky defect, number of atoms

                         

                      = 3.992

                     

                         

                      = 1.5427 g cm-3
