Question

how much charge is there on a body if one mole of electrons are added to it?

Answer 1

Hey,
Thanks for asking this question.

The answer is 1 Faraday.

Explaination-

The charge on 1 electron = 1.6 x 10^-16 Coulomb

Number of electrons in one mole = 6.02 x 10^23.

So the charge that will be added if one mole of electrons are added = (1.6 x 10^-16) x (6.02 x 10^23)
= 96485 C

= 1 Faraday.


Hope this answer helps.

Answer 2

The Avogadro Constant (the number of electrons or any other species per mole) is 6.02214086×10^23 mol^−1. The charge on one electron is 1.60217662×10^−19 C.
So, the charge on one mole of electrons is the product of these two numbers,
i.e. 96485.33289(59) C mol^−1. This is defined as one Faraday.
