Chemist
Amedeo Avogadro
Proposed in 1811 that equal volumes of gases contain equal numbers of molecules, and was ignored for nearly fifty years, until four years after he died.
Lorenzo Romano Amedeo Carlo Avogadro, Count of Quaregna and Cerreto (, also, Italian: [ameˈdɛːo avoˈɡaːdro]; 9 August 1776 to 9 July 1856) was an Italian scientist, most noted for his contribution to molecular theory now known as Avogadro's law, which states that equal volumes of gases under the same conditions of temperature and pressure will contain equal numbers of molecules. In tribute to him, the ratio of the number of elementary entities (atoms, molecules, ions or other particles) in a substance to its amount of substance (the latter having the unit mole), 6.02214076×1023 mol-1, is known as the Avogadro constant. This constant is denoted NA, and is one of the seven defining constants of the SI.
