Number of unit cells in 4g of X(atomic mass=40). Which crystallises in bcc pattern in `(N_(0)="Avogadro number")`

A

`0.1 N_(A)`

B

`2xx0.1 N_(A)`

C

`(0.1N_(A))/(2)`

D

`2xxN_(A)`

Text Solution

Verified by Experts

40 g = `N_(A)` actoms `implies ` 4 g 0.1 `N_(A)` atoms 2 atoms form 1 unit cell in bcc crystal
`:. 0.1xx N_(A) "atoms" = (0.1xxN_(A))/(2)` unit cells.
