Enter the total charge and the moles of electrons into the calculator to determine the Faraday constant. The Faraday constant is a fundamental physical constant representing the charge of one mole of electrons.

Faraday Constant Formula

The following formula is used to calculate the Faraday constant:

F = Q / n


  • F is the Faraday constant (C/mol)
  • Q is the total charge (coulombs)
  • n is the moles of electrons

To calculate the Faraday constant, divide the total charge by the moles of electrons.

What is the Faraday Constant?

The Faraday constant, often denoted by the symbol F, is the total electric charge carried by one mole of electrons. It is named after the English scientist Michael Faraday and is approximately equal to 96,485 coulombs per mole. This constant is widely used in electrochemistry to relate the amount of electric charge in coulombs to the amount of substance in moles.

How to Calculate the Faraday Constant?

The following steps outline how to calculate the Faraday Constant.

  1. First, determine the total charge (Q) in coulombs.
  2. Next, determine the moles of electrons (n).
  3. Next, gather the formula from above = F = Q / n.
  4. Finally, calculate the Faraday Constant (F) in C/mol.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
