Comprehension XI
The crystal \( \mathrm{AB} \) (rock salt structure) has molecular mass \( 6.023 y \) amu, where \( y \) is an arbitrary number in amu. If the minimum distance between cation and anion is \( y^{1 / 3} \mathrm{~nm} \) and the observed density is \( 20 \mathrm{~kg} / \mathrm{m}^{3} \).
The theoretical density of \( \mathrm{AB}(\mathrm{s}) \) in \( \mathrm{kg} / \mathrm{m}^{3} \) is
(a) \( 20.0 \mathrm{~kg} / \mathrm{m}^{3} \)
(b) \( 5.0 \mathrm{~kg} / \mathrm{m}^{3} \)
(c) \( 10.0 \mathrm{~kg} / \mathrm{m}^{3} \)
(d) \( 2.5 \mathrm{~kg} / \mathrm{m}^{3} \)
