with the Atom
Compiled by Glen E.
|Lorenzo Romano Amedeo Carlo Avogadro Count of Quaregna and Cerrato hypothesized that "equal volumes of gases at the same temperature and pressure contain the same number of particles." His hypothesis was not widely accepted until after his death when his fellow countryman Cannizzaro convinced other chemists of its validity. Both Dalton and Berzelius rejected Avogadro's hypothesis which is the main reason why so much controversy surrounded it. Avogadro coined the term "molecule" and defined it as a combination of atoms. The number of molecules in a mole of a substance is 6.022 x 1023 and is known as Avogadro's number.|
