If the similar volume of SiC and diamond are considered, which of the following is the true statemen — Solid State Chemistry Question

💡 Solution & Explanation

Number density $= Z/a^3$. For diamond, C atoms $/ V = 8 / 44.2 \approx 0.181$. For SiC, formula units $/ V = 4 / 83.0 \approx 0.0482$. The ratio is $0.181 / 0.0482 \approx 3.75$. So, C atoms in diamond are 3.75 times the SiC formula units. Therefore, correct answer is D.
