A mole is a fundamental unit used to measure the amount of a substance. It is very useful in certain instances, mainly where mass is not measurable or when it is nearly zero.
An Italian scientist, Amedeo Avogadro, came up with the size of a mole. He discovered that the number of atoms in 12 grams of carbon-12 is 6.02 x 1023. It has since been widely accepted as the number of atoms or entities in one mole of a substance.
Atoms, molecules, particles, and other units of measurement in chemistry are often measuring very small amounts of a certain substance or property. The mass of these variables are often next to none, making moles the best way to measure them.
The average mass of one mole of H2O is 18.02 grams.
