Question

what is the amount of charge possessed by 1kg of electron?
class-12

Answer 1

1e has charge of 1.602 X 10-19 C
So, 9.109 X 10-31 kg has 1.602 X 10-19 C
So, 1 Kg has = 1.602 X 10-19/(9.109 X 10-31) C

Answer 2

Charge of an electron: -1.602 * 10^-19 C

Mass of an electron: 9.11 * 10^-31 kg

Electrons in 1kg: 1/(9.11 * 10^-31) = 1.10 * 10^30.

Charge of 1kg of electrons: (1.10 * 10^30)(-1.602 * 10^-19) = -1.76 * 10^11 C
