An element (atomic mass `= 100 g//mol`) having bcc structure has unit cell edge 400 pm .Them density of the element is

A

`10.376g//cm^(3)`

B

`5.188g//cm^(3)`

C

`7.289g//cm^(3)`

D

`2.144g//cm^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`p=(ZxxM)/(a^(3)xxN_(0)xx10^(-30))=(2xx100)/((400)^(3)xx(6.02xx10^(23))xx10^(-30))`
`=5.188g//cm^(3)`
