Biography: Amedeo Avogadro was an Italian scientist, best known for Avogadro's law. This law was his crucial contribution to molecular theory, which holds that equal volumes of gases under the like conditions of temperature and pressure will contain equal numbers of molecules.

This law is formatted in terms of the Avogadro constant, which is that in 1 mole of a substance the number of elementary entities will be 6.02214076×10 to the power of 23. This is one of seven SI base units.

The law for which Avogadro is now best known was published in 1811 under the title of 'Essai d'une manière de déterminer les masses relatives des molécules élémentaires des corps, et les proportions selon lesquelles elles entrent dans ces combinaisons' ("Essay on a manner of Determining the Relative Masses of the Elementary Molecules of Bodies and the Proportions by Which They Enter These Combinations").
