An element has a bcc structure with a cell edge of `288` pm. The density of the element is `7.2 g cm^(-3)`. How many atoms are present in `208 g` of the element?

A

`6xx10^(23)`

B

`2.4xx10^(23)`

C

`24xx10^(23)`

D

`12xx10^(23)`

Text Solution

Verified by Experts

The correct Answer is:
C
`d=(ZxxM)/(a^(3)xxN)" " {:(Mto"mass of substance"),(Nto"No of atoms"):}`
`N=(2xx208)/((288xx10^(-10))^(3)xx7.2)`
`24xx10^(23)`
