Question

The electric charge on one electron is `1.602 xx 10^(-19)` coulomb. How much charge is present on 0.1 mole of `Cu^(2+)` ions ?

Answer 1

Charge on one electron `= 1.602 xx 10^(-19)C`
Charge on one mole electrons `= 6.022xx10^(23)xx1.602xx10^(-19)=96472~~1` Faraday
Charge on 0.1 mole of `Cu^(2+)` ions `= 0.1 xx 2 = 0.2` Faraday.
