A metal crystallises in FCC lattice. If edge length of the cell is `4xx10^(-8)` cm and density is `10.5 g cm^(-3)` then the atomic mass of metal is

A

101.2

B

50.6

C

202.3

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
`d=(ZxxM)/(N_(A)xxa^(3))`
`"In FCC"toZ=4`
`10.5=(4xxM)/(6xx10^(23)xx(4xx10^(-8))^(3))`
`M=101.2`
