Avogadro,s Works

1
Avogadro works in chemistry In 1811, Avogadro published an article in Journal de physique that clearly drew the distinction between the molecule and the atom. He pointed out that Dalton had confused the concepts of atoms and molecules. The "atoms" of nitrogen and oxygen are in reality "molecules" containing two atoms each. Thus two molecules of hydrogen can combine with one molecule of oxygen to produce two molecules of water. Avogadro suggested that: equal volumes of all gases at the same temperature and pressure contain the same number of molecules, which is now known as Avogadro's Principle. The work of Avogadro was almost completely neglected until it was forcefully presented by Stanislao Cannizarro at the Karlsruhe Conference in 1860. He showed that Avogadro's Principle could be used to determine not only molar masses, but also, indirectly, atomic masses.
