Avogadro, Armedeo (1776-1856)

The Italian scientist after which is named the Avogadro's Law, viz,. "equal volumes of different gases, pressure and temperature being equal, contain the same number of molecules"; or, "equal volumes of gases or vapours contain the same number of molecules".

Avogadro was the first to conclude from Dalton′s atomic theory that equal volumes of gases (at the same temperature and pressure) must contain equal number of molecules.

He proposed a correct molecular explanation for Gay-Lussac's law of combining volumes. His work provided a simple way to determine atomic weights and molecular weights of gases.
