Find the total charge in coulmb on one gram ion of nitride.

Explanation

Charge on each nitride `(N^(3-))` ion = `3 xx 1.602 xx 10^(-19) = 4.806 xx 10^(-19) "coul".`
Number of ions in a gram ion of nitride = `6.023 xx 10^(23)`
Total charge on one gram ion of nitride = `6.023 xx 10^(23) xx 4.806 xx 10^(-19) = 2.895 xx 10^(5) "coul"`.
