Italian chemist and physicist Amedeo Avogadro in 1811 advanced the hypothesis that people came to call his law and that enabled people to calculate his number.
His law, the principle, states that equal volumes of all gases under identical conditions of pressure and temperature contain the same number of molecules or atoms.
His number, also called Avogadro constant, equals 6.0221 × 10^23, the number of items in a mole.
