The pyknometric density of sodium chloride crystal is

2.165 \times {10^3}\;\mathrm{kg}\;{\mathrm{m}^{ - 3}}

while is X-ray density is

2.178 \times {10^3}\;\mathrm{kg}\;{\mathrm{m}^{ - 3}}

. The fraction of the unoccupied sites in sodium chloride crystal is :

View answer and explanation

Correct option: D

5.96 \times {10^{ - 3}}

Option D (

5.96 \times {10^{ - 3}}

) is correct because it accurately calculates the fraction of unoccupied sites based on the difference between pyknometric and X-ray densities.
