The mole is the SI unit of the amount of substance.

The number of particles e.g. atoms, ions, molecules, electrons, cows, cars are all measured in terms of moles.

 The number of particles in one mole is called the Avogadro Constant.

 It is denoted “L”.

The Avogadro Constant contain 6.023 x10 23 particles. i.e.

1mole = 6.023 x10 23 particles  =  6.023 x10 23
