Detailed Solution

Mass of one electron is $9.10 \times 10^{- 31} kg$ . Mass of one mole of electron is:

$9.10 \times 10^{- 31} kg \times 6.023 \times 10^{23} = 5.486 \times 10^{- 7} kg$

Mass of one electron is $1.602 \times 10^{- 19} Coulomb$ . Charge of one mole of electron is:

$1.602 \times 10^{- 19} \times 6.023 \times 10^{23} = 9.647 \times 10^{4} Coulomb$
