A sample of electrically neutral NaCl crystal is analysed for its density which has some unoccupied sites. Two readings where taken.
1 . Density of NaCl crystal assuming all sites are occupied = 2.178 × 103 kg m–3
2 . Density of NaCl crystal by not considering the unoccupied sites but only the occupied sites = 2.165 × 103 kg m–3.
The percentage of unoccupied sites in NaCl crystal is
1 . Density of NaCl crystal assuming all sites are occupied = 2.178 × 103 kg m–3
2 . Density of NaCl crystal by not considering the unoccupied sites but only the occupied sites = 2.165 × 103 kg m–3.
The percentage of unoccupied sites in NaCl crystal is
- 5.96 × 10–2
- 5.96 × 10–1
- 5.96
- 8.68
Answer
(B) 5.96 × 10 –1
