How many Cs atoms can be convered to `Cs^(+)` ions by 1 joule energy if `IE_(1)` for Cs is 376 `KJ "mole"^(-1)`

`1.6xx10^(18)`

`1.6xx10^(10)`

`5.8xx10^(14)`

`5.8xx10^(25)`

Text Solution

Verified by Experts

The correct Answer is:

`IE_(1)` of `Cs=376 KJ = 3.76xx10^(5)` J/1 mole
`37.6xx10^(5) J to 6.023xx10^(23)` atoms
`1J to ?`
