best_answer

As the mass of one electron is equal to 9.11\times10^{-31}kg

Therefore, Mass of 1 mole or 6.022\times10^{23} electrons = (9.11\times10^{-31})\times(6.022\times10^{23}) = 5.48\times10^{-7}kg.

Charge on one electron is 1.602\times10^{-19}\ coulomb.

Therefore, the charge on 1 mole of electrons will be:

\Rightarrow (1.602\times10^{-19})\times(6.022\times10^{23}) = 9.65\times10^{4}\ coulombs.
