In a solid, oxide ions are arranged in ccp. Cations 'A' occupy one-sixth of the tetrahedral voids and cations 'B' occupy one-third of the octahedral voids. Which of the following is the correct formula of the oxide?

Options:

Answer:

Solution:

Cation $A = \frac{1}{6} \times 8 = \frac{8}{6} = \frac{4}{3}$
Cation $B = \frac{1}{3} \times 4 = \frac{4}{3}$
$O^{2 -} = 8 \times \frac{1}{8} + 6 \times \frac{1}{2} = 4$
A : B : $O^{2 -} = \frac{4}{3} : \frac{4}{3} : 4 = 1 : 1 : 3$
