According to Chemist George M. Bodner, Avogadro’s number was not discovered by Amadeo Avogadro. Avogadro was a lawyer who tokes interest in mathematics and physics. Avogadro was most credited for his hypothesis about the equal volumes of different gases at the same temperature and pressure containing the same number of particles. Italian scientist Stanislao Cannizzaro used Avogadro's hypothesis to develop a set of atomic weights by comparing the masses of equal volumes of gas (visionlearning.com). Mr. Bodner states that French Physicists Jean Baptiste Perrin was the first to use the term Avogadro’s number. Based on his work on Brownian motion in 1909, Perrin reported an estimate of Avogadro’s number. To accurately determine Avogadro’s number requires the measurement of a single quantity on both atomic and macroscopic scales, with the use of the unit of measurement. This was possible because American Physicist Robert Millikan measured the change on an election. The charge on a mole of electrons for some time and is the constant called the Faraday. The estimate of the value of a faraday is 96,485.3383 coulombs per mole of electrons. The estimate of the charge on an election base is 1.60217653 x 10^-19 coulombs per electron. Divided the charge of a mole of an election obtains the value of 6.02214154 x 10^23 particles per mole. According to Bender oxygen and hydrogen are elements other than carbon used to define mole. A mole is the quantity of an element that weighs out in grams the amount of an element specified by the atomic weight.
