Amedeo Avogadro | Biography, Law, Discoveries, & Facts
Amedeo Avogadro was an Italian physicist who studied gas volume, pressure, and temperature. He lived from August 9, 1776, to July 9, 1856. He developed Avogadro’s law, which asserts that all gases contain the same number of molecules per volume at the same temperature and pressure. Avogadro is now regarded as a key figure in the development of atomic theory.
Biography
Amedeo Avogadro, born in Turin, Italy, on the 9th of August in 1776. His aristocratic ancestors were his forefathers. Filippo, his father, was a Count who served as a magistrate and senator. Anna Vercellone of Biella, his mother, was a noblewoman.
From his father, Amedeo Avogadro gained the title of Count. In truth, Count Lorenzo Romano Amedeo Carlo Avogadro di Quaregna e di Cerreto was Amedeo Avogadro’s entire name.
Avogadro was a brilliant mathematician. He received his PhD in canon law in 1796, when he was only 20 years old, and began practising as an ecclesiastical lawyer.
Even though he had followed in his family’s footsteps

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,

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
