His law reconciled the chaos of gas behavior into one clean rule: equal volumes, equal conditions, equal numbers of molecules. The constant named for him—6.02214076×10²³ particles per mole—became one of the seven pillars holding up the entire international system of measurement.

Lorenzo Romano Amedeo Carlo Avogadro, Count of Quaregna and Cerreto, was born in Italy on 9 August 1776. He turned his attention to molecular theory and arrived at the insight now called Avogadro's law: that equal volumes of gases under identical temperature and pressure contain equal numbers of molecules. The principle clarified relationships that had confounded earlier chemists. Long after his death on 9 July 1856, the scientific community formalized the tribute: the ratio of elementary entities in a substance to its amount—the Avogadro constant, NA—was fixed at 6.02214076×10²³ mol⁻¹ and des…
