The number of Na+ ions present in one unit cell=12×1/4+1=4 atoms per unit cell
The number of Cl- ions present in one unit cell=6×1/2+8×1/8=4 atoms per unit cell
So, each unit cell has 4atoms of each Na+ and Cl-. Hence, there are total 4 molecules of NaCl in each unit cell. I hope u will satisfied my answer.
