SpletThe amount of a substance equal to its atomic mass or molar mass in grams is 1 mole of a substance. iii. Thus, one mole of a substance is defined as the amount of the substance that contains the number of particles (atoms, molecules, ions or electrons, etc.) as present in 0.012 kg of carbon–12. iv. Splet1 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.

SpletOne mole is defined as the amount of substance having molar mass, occupying 22.4 lt of volume and having Avogadro's number of particles. Avogadro's number (N)=6.023* (10^23) number of particles.
