Atoms, ions and molecules are very tiny particles and it is impossible to measure out a dozen or even a hundred of them. Instead, chemists weigh out a very large number of particles. This number is the 6.0221367\u00d71023<\/sup>, ions or molecules. An amount of substance containing 6.0221367\u00d71023<\/sup> particles is called a mole (abbreviated to mol).<\/p>\n

So, a mole of the element aluminium is 6.0221367\u00d71023 <\/sup>atoms of aluminium and a mole of the element iron is 6.0221367\u00d71023 <\/sup>atoms if iron.<\/p>\n","protected":false},"excerpt":{"rendered":"
