Question

Calculate the electric charge carried by one electron on the basis of Faraday’s constant.

Answer 1

We know that

Charge of one electron = `F/N_A`    ...(i)

Where

F = 96500 C mol⁻¹

N_A = 6.022 × 10²³ mol⁻¹

Putting these values in the equation, (i) we get

Charge of one electron = `96500/(6.022 xx 10^23)`

= 1.602 × 10⁻¹⁹ C

∴ The electric charge carried by one electron on the basis of Faraday’s constant is 1.602 × 10⁻¹⁹ C.
