An element X (At,wt = 80 g//mol) having ...

An element `X (At,wt = 80 g//mol)` having fcc structure, calculate the number of unit cells in `8g of X`

A

`9.4xxN_(A)`

B

`0.1xxN_(A)`

C

`4xxN_(A)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
4
Effective no of atoms in a unit cell `=4`
No. of atoms `=(8)/(80)xxN_(A)`
`:." "`No. of unit cell`=(N_(A))/(10)xx(1)/(4)`
