Moles are a unit of measurement for chemicals, just as meters are measurement units for length and grams are measurement units for mass.

The mole is a unit of measurement for the amount of substance or chemical amount. It is one of the base units in the International System of Units, and has the unit symbol mol.[1]
The name mole is an 1897 translation[2][3] of the German unit Mol, coined by the chemist Wilhelm Ostwald in 1893,[4] although the related concept of equivalent mass had been in use at least a century earlier. The name is derived[5] from the German word Molekül (molecule).
The mole is defined as the amount of substance that contains as many elementary entities (e.g., atoms, molecules, ions, electrons) as there are atoms in 12 g of the isotope carbon-12 (12C).[1] Thus, by definition, one mole of pure 12C has a mass of exactly 12 g. The experimentally determined value of a mole as adopted by CODATA in 2006 is 6.02214179(30)×1023
.[6] Recent measurements give the value 6.02214078(18)×1023
