When was avogadros law created

Amadeo Avogadro, , lived in a time of flux and uncertainty, in physics and in the governance of his community. In physics, the very nature of the elements was debated by the leading scientists: Was oxygen an atom or a diatomic molecule? His discovery of the fundamental numerical property of gases underlies our understanding of the molecular world. His political activities cost him his professorship at the University of Turin, but he was reinstated in the next political cycle, not long after. His full name was Lorenzo Romano Amedeo Carlo Avogadro, from a family with a long history in the legal profession.

Their name derives from avvocato , Italian for lawyer. He followed the family profession for some years, then, self-taught, began to work in physics. He became professor of physics at the Academy at Vercelli, and later at the University of Turin. Much of physics, at the time, was focused on the nature of gases. The French physicist Joseph Louis Gay-Lussac observed that, in reactions of gases, the relative volumes of reactants and products appeared to be in the ratio of small whole numbers.

Avogadro went on from there [ 1 ]. There are a few ways to write this gas law , which is a mathematical relation. It may be stated:. Avogadro's law also means the ideal gas constant is the same value for all gases, so:. There are a few important consequences of the law being true. Say you have 5. What will be the new volume of the gas if the quantity is increased to 1. Select the appropriate form of the law for the calculation. In this case, a good choice is:. Rewriting to solve for x give you:.

Avogadro did not actually use the word atom ; at the time the words atom and molecule were used almost interchangeably. According to Avogadro, the molecule of oxygen had split into two atoms in the course of forming water vapor. In addition, Avogadro was not part of an active community of chemists: the Italy of his day was far from the centers of chemistry in France, Germany, England, and Sweden, where Berzelius was based.

Avogadro was a native of Turin, where his father, Count Filippo Avogadro, was a lawyer and government leader in the Piedmont Italy was then still divided into independent countries. After obtaining his formal degrees, he took private lessons in mathematics and sciences, including chemistry.
