A compound having bcc geometry has atomic mass 50. Calculate density of unit cell if its edge length is 290 pm.

Text Solution

Verified by Experts

For bcc geometry, number of atoms per unit cell (Z) = 2
Atomic mass (A) = 50
Edge length (a) `= 290xx10^(-10)cm`
Density `(rho)= ?`
`rho =(Z xx A)/(N_(0)xx a^(3))=(2xx50)/(6.02xx10^(23)xx(290xx10^(-10))^(3))=6.82 g//cm^(3)`.
