A group `IV` A element with a density of `11.35 g//cm^(3)` crystallises in a face centered cubic lattice whose unit cell edge length is `4.95 Å` .Calculate its atomic mass

A

`207.2 g//mol`

B

`180 g//mol`

C

`109.9 g//mol`

D

`280.8 g//mol`

Text Solution

Verified by Experts

The correct Answer is:
d
`d = (GAM xx Z)/(N_(A) xx a^(3))`
for `PC C,Z = 4`
`GMA = 207.2 g//mol`
