A sample of AIF(3) contains 3.0 xx 10^(2...

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

A

`9.0 xx 10^(24)`

B

`3.0 xx 10^(24)`

C

`0.75 xx 10^(24)`

D

`1.0 xx 10^(24)`

Text Solution

Verified by Experts

d) `therefore` `3F^(-)` = 1 Formula units of AI`F_(3)`
`therefore` `3.0 xx 10^(24)F^(-)` = `1 xx 10^(24)` formula units of `AIF_(3)`
