1.	A compound having bcc geometry has atomic mass 50. Calculate the density of the unit cell, if the edge length is 290pm.
Answer» `6.81gcm^(-3)` `3.40gcm^(-3)` `13.62gcm^(-3)` NONE of these Solution :(a) density of unit CELL, `d=(ZxxM)/(N_(A)xxa^(3))` `d=(2xx50)/((290xx10^(10))^(3)xx6.023xx10^(23))=6.81g//cm^(3)`
