Faraday Constant
The electric charge carried by one mole of electrons.
Formula / equation
F = 96,485 C/mol
Unit
C/mol
In depth
The constant is the product of the elementary charge and the Avogadro constant, and it is the bridge between the electrical and chemical worlds. It converts moles of electrons in a half-equation into coulombs, allowing electrolysis yields and cell energies to be calculated.
Examples in the real world
Depositing one mole of copper from Cu²⁺ requires 2 × 96,485 = 192,970 C.
