Hello there,

We know that 1 mole of any quantity has 6.022 × 10^23 molecules. So the same way, 1 mole of electrons has 6.022 × 10^ 23 electrons.

Now the total charge is given by ;  q = ne

where n is the no. of electrons and e is the charge on a single electron.

Hence charge on 1 mole of electrons is =

6.022 × 10^23 × 1.6 × 10^-19

= 9.6352 × 10^4 Columb

Hope it helps.
