What are the avogadros inventors?

Avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain an equal number of molecules, was formulated by the Italian scientist Amedeo Avogadro in 1811. While Avogadro himself is credited with the concept, the actual term "Avogadro's number," representing the number of particles in one mole of a substance (approximately (6.022 \times 10^{23})), was named in his honor later on. Avogadro's contributions were pivotal in the development of molecular theory and stoichiometry in chemistry.
