An element cyrstallizes in a structure having F.C.C. unit cell of an edge 200pm. Calculate the density if 200gm of it contains `24xx10^(23)` atoms

A

`41.6gm//cm^(2)`

B

`42.6gm//cm^(2)`

C

`43.6gm//cm^(3)`

D

`44.6gm//cm^(2)`

Text Solution

Verified by Experts

The correct Answer is:
1
`rho=(z.m)/(N_(0)a^(3))`
mass of `24xx10^(23) "atoms"=200g`
mass of `6xx10^(23)"atoms"=50g`
`m=50,z=4`
