  AVOGARDO Amedeo Avogadro , in full  Lorenzo Romano Amedeo Carlo Avogadro, conte di Quaregna e Cerreto was born on   August  9, 1776, Turin, in the  Kingdom of Sardinia  and Piedmont [Italy].Italian mathematical physicist who showed in what became known as  Avogadro’s law  that, under controlled conditions of  temperature  and  pressure , equal volumes of  gases  contain an equal number of  molecules .                                         In honor of Avogadro's contributions to molecular theory, the number of molecules per mole of substance is named the " Avogadro constant ",  N A . It is exactly  6.02214076×10 23  mol −1 . [7]  The Avogadro constant is used to compute the results of chemical reactions. It allows chemists to determine the amounts of substances produced in a given reaction to a great degree of accuracy. Avogadro is chiefly remembered for his molecular  hypothesis , first stated in 1811, in which he claimed that equal volumes of all  gases  a
