Answer
D) one mole of electrons.
Step-by-step explanation
Faraday's constant describes the amount of charge associated with one mole of electrons.
The Faraday constant represents the amount of electric charge carried by one mole, or Avogadro's number, of electrons.
The Faraday constant is denoted by the symbol F and it is named after Michael Faraday. It is expressed in coulombs per mole (C/mol).
The correct answer is D) one mole of electrons.
