He proposed in 1811, his famous hypothesis, now known as Avogadro's Law. The law stated that equal volumes of all gases at the same temperature and pressure contain the same number of molecules.

His law helped to overcome John Dalton's atomic theory. Avogadro also distinguished between an atom and a molecule, to determine a table of atomic weights.

Correction and standardization of atomic weights began in 1858, when Stanislao Cannizzaro, an Italian chemist, reminded other chemists about Avogadro's work.
