 The total number of atoms in 0.5 mol = 0.5 x 6.023 x 10 23   = 3.011 x 10 23

The number of octahedral voids =  3.011 x 10 23
 
The number of tetrahedral voids =  3.011 x 10 23 x2 = 6.023 x 10 23 (number of tetrahedral voids is twice the number of atoms in hcp arrangement.)
 
Thus the total number of voids  =  3.011 x 10 23 +  6.023 x 10 23  = 9.033 x 10 23
