Solution
12
- The molecular mass of Hydrogen is 1 gram and has a single electron in its configuration as it is the first most element of the periodic table.
- The 12 grams of Hydrogen contains 12 moles of the electrons in it. Usually, the electricity will be passed through the free electrons.
- The 12 grams of Hydrogen contains 12 electrons which are free electrons.
- Each free electron is capable of conducting 1 Faraday of electricity.
- Since 12 grams of Hydrogen are having 12 electrons in it, we require 12 Faraday of electricity.
