Total no. of voids in `0.5` mole of a compound forming hexagonal closed packed structure are :

Options

A. `6.022xx10^(23)`
B. `3.011xx10^(23)`
C. `9.033xx10^(23)`
D. `4.516xx10^(23)`

Answer

C

Explanation

No. of voids per molecule `=3`
No. of voids in `0.5` mole molecules
`=3xxN_(0)xx0.5`
`=3xx6.022xx10^(23)xx0.5`
`=9.033xx10^(23)`
