Question

How many Faradays of electricity are required to liberate 2 moles of hydrogen gas in electrolysis of a solution ?

Answer 1

2 Faraday's are required.

Answer 2

Answer: 2Faradays

Explanations:

First calculate mass required by using moles=mass/molar mass

Where by moles=2moles

Molar mass Hydrogen gas=2g/mol

Then proceed with the general formula of finding number of Faraday by using First law of electrolysis
