Question
If the volume occupied by a unit cell of NaCl is 4.7 × 10–23 ml, then the volume of a crystal of NaCl weighing 1.0 g is
Options
A.2.13 × 1022 ml
B.8.03 × 10−25 ml
C.0.48 ml
D.0.12 ml
Solution
21. Number of NaCl formula units in 1 gm = $\frac{1}{58.5} \times \left( 6 \times 10^{23} \right)$.
Each unit cell contains 4 NaCl formula units and hence, volume of crystal
$= \frac{6 \times 10^{23}}{58.5 \times 4} \times 4.7 \times 10^{- 23} = 0.12\text{ml}$
