The Faraday Constant is 96485.3399 Coulombs per Mole. The Faraday constant is the magnitude of electric charge per mole of electrons. This constant is named after Michael Faraday. Related to Faraday's constant is the "faraday", a unit of electrical charge. It is much less common than the coulomb, but sometimes used in electrochemistry. This constant, the Faraday constant (symbol: F), is expressed in Coulomb per mole.
