Emily O'brochta Abigail Weiler Julia Morici Rose Klinger Isabella Gratzianna Peyton Stark HESCH, NICHOLAS Aidan Trapp U9 Boys Travel Chapter 9. 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 C. 4. H. 10. + 13 O. 2. ---> 8 CO. 2. + 10 H. 2. O .
