The charge in coulombs on 1 g ion of `N^(3-)` isA. 96500B. `2.89xx10^(5)`C. `1.45xx10^(6)`D. `6xx10^(23)`

Answer» Correct Answer - B
One `N^(3-)` ion has 3 units of electric charge
`therefore` 1 g ion of `N^(3-)` has `3xx6.023xx10^(23)` electrons
or 1 g ion of `N^(3-)` has `3xx6.023xx10^(23)` electrons
or 1 g ion `N^(3-)` has `3xx96500` coulomb charge
`=289500=2.89xx10^(6)C`
