How many electrons will have a total charge of 1 Coulomb?

1.	How many electrons will have a total charge of 1 Coulomb?
Answer» Given : Charge = 1 Coulomb Number of electrons = ? 1 Faraday = 96500 C per mol electrons ∵ 96500 C electric charge is present on 1 mol electrons ∴ 1C charge is present on \(\frac{1}{96500}\) mol electrons ∴ Number of electrons = \(\frac{1}{96500}\) x 6.022 x 10²³ = 6.24 × 10¹⁸ electrons ∴ 1 Coulomb charge is present on 6.24 × 10¹⁸ electrons.

Answer»

Given :

Charge = 1 Coulomb Number of electrons = ?

1 Faraday = 96500 C per mol electrons

∵ 96500 C electric charge is present on 1 mol electrons

∴ 1C charge is present on \(\frac{1}{96500}\) mol electrons

∴ Number of electrons = \(\frac{1}{96500}\) x 6.022 x 10²³

= 6.24 × 10¹⁸ electrons

∴ 1 Coulomb charge is present on 6.24 × 10¹⁸ electrons.
