A metal crystallises in a bcc lattice ,its unit cell edge length in about `300` pm and its molar mass is about `50g mol^(-1)` what would be the density of the metal (in g `cm^(-3))`?

A

3.1

B

6.2

C

9.3

D

12.4

Text Solution

Verified by Experts

The correct Answer is:
B
Density , `d=(ZxxM)/(N_Axxa^3)=(2xx50)/(6.02xx10^23xx(3xx10^(-8))^3)`
`=6.15=6.2gcm^(-3)`
