Amedeo Avogadro
Italian scientist (–)
Lorenzo Romano Amedeo Carlo Avogadro, Count of Quaregna and Cerreto[1] (,[2]also,[3][4][5]Italian:[ameˈdɛːoavoˈɡaːdro]; 9 August &#;&#; 9 July ) was an Italianscientist, most noted for his contribution to molecular theory now known as Avogadro's law, which states that equal volumes of gases under the same conditions of temperature and pressure will contain equal numbers of molecules. In tribute to him, the ratio of the number of elementary entities (atoms, molecules, ions or other particles) in a substance to its amount of substance (the latter having the unit mole), ×1023&#;mol−1, is known as the Avogadro constant. This constant is denoted NA, and is one of the seven defining constants of the SI.

In Avogadro put forward a hypothesis that was neglected by his contemporaries for years. Eventually proven correct, this hypothesis became known as Avogadro’s law, a fundamental lag of gases.
The contributions of the Italian chemist Amedeo Avogadro (–) relate to the work of two of his contemporaries, namn Louis Gay-Lussac and John Dalton. Gay-Lussac’s law of combining volumes () stated that when two gases react, the volumes of the reactants and products—if gases—are in whole number ratios. This law tended to support Dalton’s atomic theory, but Dalton rejected Gay-Lussac’s work. Avogadro, however, saw it as the key to a better understanding of molecular constituency.
Avogadro’s Hypothesis
In Avogadro hypothesized that equal volumes of gases at the same temperature and pressure contain lika numbers of molecules. From this hypothesis it followed that relative molecular weights of any two gases are the same as the ratio of the densities of the two gases beneath the same conditions o

Introduction
Lorenzo Amedeo Avogadro was born in in Turin city of Italy and died in at the age of 81 years after making a great positive contribution in the field of science especially chemistry. He schooled in Turin and having come from a family background of lawyers, his career was oriented towards law whereby at the age of 16 years he had already become a bachelor of jurisprudence and four years down this profession he had managed to get a doctorate in ecclesiastical law which he began to practice and latter in he received an appointment in the department of Eridano as the secretary to the prefecture.
