History. About 200 years ago scientists needed a unit of measure that connected the mass of a molecule or atom with how many of them there were. . Amadeo Avogadro proposed his hypothesis in 1811. At that time, there was no data on the number of particles in a mole, or an agreement on any atomic weights or the standard. . 2. .. 2.)
