QUESTION: 20

How many unit cells are present in a cube-shaped ideal crystal of NaCl of mass 1.0 g?(Atomic weights of Na = 23 and Cl = 35.5)

Solution:

Gram formula mass of NaCl = (23 + 35.5)g = 58.5g
Number of formula units of NaCl in 1.0g of NaCl = 6.02 x 1023/58.5 x1.0
There are four formula units per unit cell in NaCl
∴ Number of unit cells = 6.02 x 10 23 x1.0/58.5 x4 = 2.57 x 1021
