A sample of `AIF_(3)` contains `3.0 xx 10^(24)` `F^(-)` ions. The number of formula units of the sample are

A

`2.0xx10^(24)`

B

`1.0xx10^(24)`

C

`5xx10^(23)`

D

`9.0xx10^(20)`.

Text Solution

Verified by Experts

The correct Answer is:
B
`3F^(-)` are present in one `AlF_(3)` formula unit No. of `AlF_(3)` formula units `=(3.0xx10^(24))/(3)=1.0xx10^(24)`
