An atomic solid crystalliuzen in a body centre cubic lattice and the inner surface of the atoms at the adjacent corner are separated by `60.3 "pm"` .If the atomic mass of A is 48, then density of the solid , is nearly :

A

2.7 g/acc

B

5.07 g/cc

C

3.5 g/cc

D

1.75 g/cc

Text Solution

Verified by Experts

The correct Answer is:
D
`a-2r=60.3` pm
bcc `4r=sqrt(3)a, d=(2xx48)/(N_(0)xx(4.5)^(3)xx10^(-24))=1.75g//u`
