In chemistry, one often uses a unit of charge known as the faraday, f, which has the magnitude of the charge of 1 mole of electrons. how many coulombs are there in a faraday

 96500 Coulombs are there in a Faraday.

Explanation:-

It is given that 1 mole of electrons has charge of 1 Faraday.

Moles of electron = 1 mole

According to mole concept:

1 mole of an atom contains number of particles.

We know that:

Charge on 1 electron =

Charge on 1 mole of electrons =      

Thus 96500 C= 1 Faraday

Thus 96500 Coulombs are there in a Faraday.
