Question

Calculate the mass and charge of one mole of electrons.

Answer 1

Mass of one electron = 9.10939 × 10^–31 kg
Mass of one mole of electron = (6.022 × 10²³) × (9.10939 ×10^–31 kg)
= 5.48 × 10^–7 kg
Charge on one electron = 1.6022 × 10^–19 coulomb
Charge on one mole of electron = (1.6022 × 10^–19 C) (6.022 × 10²³)
= 9.65 × 10⁴ C
