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

A

`9*0xx10^(24)`

B

`3*0xx10^(24)`

C

`0*75xx10^(24)`

D

`1*0xx10^(24)`

Text Solution

Verified by Experts

The correct Answer is:
D
`3F^(-) -= 1` Formula unit `(AIF_(3))`
`3*0xx10^(24)F^(-) = 1xx10^(24)` Formula unit `(AIF_(3))`
