An element (atomic mass ) having BCC structure has a unit cell edge length of . Calculate its densit — Solid State Chemistry Question

💡 Solution & Explanation

For BCC, $Z=2$. Convert $a=400\text{ pm}=4\times10^{-8}\text{ cm}$. Density is $\rho=\frac{ZM}{N_Aa^3}=\frac{2\times100}{6.02\times10^{23}\times(4\times10^{-8})^3}\approx5.19\text{ g/cm}^3$.
