The Faraday constant represents the amount of electric charge carried by a one mole , or Avogadro's number, of electron s. It is an important constant in chemistry, physics, and electronics, and is commonly symbolized by the italic uppercase letter F . It is expressed in coulomb s per mole (C/mol).
The Faraday constant can be derived by dividing the Avogadro constant , or the number of electrons per mole, by the number of electrons per coulomb. The former is equal to approximately 6.02 x 10 23 , and the latter is approximately 6.24 x 10 18 . Therefore:
F = (6.02 x 10 23 ) / (6.24 x 10 18 )
= 9.65 x 10 4 C/mol
This is accurate to three significant figures.
