Question

An element having bcc geometry has atomic mass $50$ . Calculate the density of the unit cell, if its edge length is $290$ pm.

Open in App

Solution

$d e n s i t y = \frac{Z \times M}{a^{3} \times N_{A}}$
$d e n s i t y = \frac{2 \times 50}{(290 \times 10^{- 10})^{3} \times 6.022 \times 10^{23}}$
$= 6.81 g / c m^{3}$
