The number of unit cells in `58.5 g` of `NaCl` is nearly

A

`6xx10^(20)`

B

`3xx10^(22)`

C

`1.5xx10^(23)`

D

`0.5xx10^(24)`

Text Solution

Verified by Experts

The correct Answer is:
C
`58.5 g (1 "mol")` of NaCl contains
`=6.022xx10^(23)` units
One unit cell constains 4 NaCl units
`:.` No of unit cells present
`=(6.022xx10^(23))/4=1.5xx10^(23)`
