How many electrons are in one mole
Web1 mole of electrons contains the Avogadro constant, L, electrons - that is 6.02 x 10 23 electrons. You would also be given that in an exam if you needed to use it. That means the 1 mole of electrons must carry 6.02 x 10 23 x 1.60 x 10 -19 coulombs = 96320 coulombs This value is known as the Faraday constant. WebThe mole is defined as exactly 6.022 140 76 × 1023 elementary entities. Depending on the nature of the substance, an elementary entity may be an atom, a molecule, an ion, an ion pair, or a subatomic particle such as a proton.
