Amedeo avogadro cause of death
- •
In 1811 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 law of gases.
The contributions of the Italian chemist Amedeo Avogadro (1776–1856) relate to the work of two of his contemporaries, Joseph Louis Gay-Lussac and John Dalton. Gay-Lussac’s law of combining volumes (1808) 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 1811 Avogadro hypothesized that equal volumes of gases at the same temperature and pressure contain equal 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 under the same conditions of temperature and pressure.
Avogadro also astutely reasoned that simple

Lorenzo Romano Amedeo Carlo Avogadro, Count of Quaregna and Cerreto (August 9, 1776 – July 9, 1856), was an Italian chemist who provided the solution to important problems in chemistry by postulating that equal volumes of gas at the same temperature and pressure contain equal numbers of molecules. The term "Avogadro's number" is applied to the number of carbon atoms in 12 grams of pure carbon. Although his theories received scant acceptance in his lifetime, he devoted his life to the pursuit of science, and his ideas were vindicated soon after his death.
Biography
Amedeo Avogadro was born in Turin, the son of Cavaliere Philippo Avogadro and Anna Vercellone di Biella. His father was a descendant of an ancient family with a long history in the legal profession.
Avogadro received a degree in philosophy in 1789, and a baccalaureate in law in 1792. He was awarded a doctorate in ecclesiastical law at the early age of 20. He then established a legal practice that he kept until about 1800, when he began doing research in physics. In 1809,

Amedeo Avogadro
Italian scientist (1776–1856)
Lorenzo Romano Amedeo Carlo Avogadro, Count of Quaregna and Cerreto[1] (,[2]also,[3][4][5]Italian:[ameˈdɛːoavoˈɡaːdro]; 9 August 1776 – 9 July 1856) 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), 6.02214076×1023 mol−1, is known as the Avogadro constant. This constant is denoted NA, and is one of the seven defining constants of the SI.
Biography
Amedeo Avogadro was born in Turin to a noble family of the Kingdom of Sardinia (now part of Italy) in the year 1776. He graduated in ecclesiastical law at the late age of 20 and began to practice. Soon after, he dedicated
