A comprehensive biography of Avogadro can be found here: http://www.bulldog.u-net.com/avogadro/avoga.html The mole is taught in every introductory chemistry class one can take at the college level. Here's an example of a chemistry course: http://antoine.frostburg.edu/chem/senese/101/moles/index.shtml There is an entire day dedicated to commemorating Avogadro's Number. National Mole Day: http://www.moleday.org/ Sparknotes is a great resource for quick learning. You can explore all you ever wanted to know about chemistry here: http://www.sparknotes.com/chemistry/ "The primary unit for the amount of substance in a chemical element is the mole, and if you are talking about the stoichiometry of a reaction, the mole is the basis for that."
