Defining the Mole

Return to Chemistry Index Page

A mole is a unit used in chemistry to help define a quantity of a compound. Before the discovery of the mole

by Amadeus Avogadro there was no real easy way to make standard quantities in making formulas. A mole represents

6.022  X 10²³    Particles or molecules or atoms of a particular substance  whether it is a element or a compound. In other words for example: whether

you have a mole of Au (gold) or a mole of Fe (Iron) you have the same number atoms of that element but you will have different mass, because each atom weighs

different due to the number of protons and neutrons in the nucleus of the atom.
