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

Answer»

Solution :Charge on each NITRIDE `(N^(3-))` ION
`=3xx1.602xx10^(-19)=4.806xx10^(-19)` coulomb.
Number of IONS in a gram ion of nitride `=6.023xx10^(23)`
Total charge on ONE gram ion ofnitride
`=6.023xx10^(23)xx4.806xx10^(-19)`
`=2.895xx10^(5)` coulomb.
