Avogadro's law is one of the three main gas laws. It states that equal volumes of gas (at the same temperature and pressure) contain the same number of molecules, regardless of the nature of the gas. It is named after Italian intellectual Amedeo Avogadro (1776-1856), who first enunciated it in 1811.[1]
Avogadro's law was widely ignored during Avogadro's own lifetime, and was not generally accepted until the 1860s.[2] It was rediscovered at least three times in the intervening period.
