In recognition of his idea, the number of fundamental particles in a mole of substance is called avogadro's number although avogadro had no idea what the number of particles in equal volumes of gases was, and did nothing to measure it, his hypothesis did lead to the eventual determination of this number, 602 x 10 23.
