Calculate the total mass and charge on 1 mole of electrons.

Open in App

Solution

Knowing that the mass of electrons = 9.11X 10^-31Kg. and charge on one electron = 1.6X10^-19C.
Mass of 1 electron = 9.11X 10^-31Kg.
Mass of one mole of electron = 9.11X 10^-31X 6.022 X 10²³
= 5.48 X 10^-7Kg.
(b) Charge on one electron = 1.6X10^-19C. X 6.022 X 10²³
= 9.64X 10⁴Columbs.
