The volume effectively occupied by a single CsCl ion pair in the crystal is — Solid State Chemistry Question

💡 Solution & Explanation

Volume of 1 formula unit = $M / (d \times N_A) = (132.5 + 35.5) / (3.5 \times 6 \times 10^{23}) = 168 / (21 \times 10^{23}) = 8 \times 10^{-23} \text{ cm}^3$ (ml). Therefore, correct answer is B.
