Avogadro was highly intelligent. In 1796, when he was only 20, he was awarded a doctorate in canon law and began to practice as an ecclesiastical lawyer. Although he had followed the family tradition by studying law, he gradually lost interest in legal matters. He found science was much more intellectually stimulating.

Beginning in 1800 Avogadro privately pursued studies in mathematics and physics, and he focused his early research on electricity. In 1804 he became a corresponding member of the Academy of Sciences of Turin, and in 1806 he was appointed to the position of demonstrator at the academy's college.
In 1811 Avogadro published a paper in Journal de Physique, the French Journal of Physics. He said that the best explanation for Gay-Lussac's observations of gas reactions was that equal volumes of all gases at the same temperature and pressure contain equal numbers of molecules. This is now called Avogadro's law.

Amedeo AvogadroAmedeo Avogadro (August 9, 1776–July 9, 1856) was an Italian scientist known for his research on gas volume, pressure, and temperature. He formulated the gas law known as Avogadro's law, which states that all gases, at the same temperature and pressure, have the same number of molecules per volume.Apr 28, 2019
Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules". For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
The MOLE (mol) is a unit of measurement that is the amount of a pure substance containing the same number of chemical units (atoms, molecules etc.) as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.022 X 1023).
In fact, Amedeo Avogadro’s full name was Count Lorenzo Romano Amedeo Carlo Avogadro di Quaregna e di Cerreto – quite a mouthful! Avogadro was highly intelligent. In 1796, when he was only 20, he was awarded a doctorate in canon law and began to practice as an ecclesiastical lawyer.
Amedeo Avogadro is best known for his hypothesis that equal volumes of different gases contain an equal number of molecules, provided they are at the same temperature and pressure. His hypothesis was rejected by other scientists. It only gained acceptance after his death. It is now called Avogadro’s law. Avogadro was also the first scientist ...
Avogadro’s Contributions to Science. In the early 1800s, scientists’ ideas about the particles we now call atoms and molecules were very limited and often incorrect. Avogadro was deeply interested in finding out how the basic particles of matter behave and come together to form chemical compounds.
In 1820 Avogadro became professor of mathematical physics at the University of Turin. Unfortunately, this post was short lived because of political turmoil. Avogadro lost his job in 1823. Avogadro was reappointed in 1833 and remained in this post until, at the age of 74, he retired in 1850.
Avogadro’s constant is the number of particles (atoms or molecules) in one mole of any substance. For example, 12 grams of carbon contains 6.02214129 x 10 23 carbon atoms. Avogadro’s constant is an enormous number.
Avogadro’s Life. Amedeo Avogadro was born in Turin, Italy, on August 9th, 1776. His family background was aristocratic. His father, Filippo, was a magistrate and senator who had the title of Count. His mother was a noblewoman, Anna Vercellone of Biella. Amedeo Avogadro inherited the title of Count from his father.
He said that the best explanation for Gay-Lussac’s observations of gas reactions was that equal volumes of all gases at the same temperature and pressure contain equal numbers of molecules. This is now called Avogadro’s law. He published it when he was working as a physics teacher at the College of Vercelli.
Avogadro believed that particles could be composed of molecules and that molecules could be composed of still simpler units (which we now call "atoms"). The number of molecules in a mole (one gram molecular weight) was termed Avogadro's number (sometimes called Avogadro's constant) in honor of Avogadro's theories.
Following in his family's footsteps, he studied ecclesiastical law and began to practice on his own before eventually turning his attention to the natural sciences. In 1800, Avogadro began private studies in physics and mathematics. His very first experiments were conducted with his brother on the subject of electricity.
In 1815, he married Felicita Mazzé; the couple had six children. Some historical accounts indicate that Avogadro sponsored and aided a group of people planning a revolution on the island of Sardinia, which was ultimately stopped by the concession of Charles Albert's modern Constitution ( Statuto Albertino ).
In his writings, Avogadro referred to three different types of "molecules:" integral molecules (most similar to what scientists call molecules today), constituent molecules (those that are part of an element), and elementary molecules (similar to what scientists now call atoms).
He formulated the gas law known as Avogadro's law , which states that all gases, at the same temperature and pressure, have the same number of molecules per volume. Today, Avogadro is considered an important early figure in atomic theory.
Avogadro wrote a memoria (concise note) in which he described the experimental gas law that now bears his name. He sent this memoria to De Lamétherie's Journal de Physique, de Chemie et d'Histoire naturelle, and it was published in the July 14, 1811 issue.
Additionally, his ideas were likely neglected because they contradicted those of more famous scientists. In 1814, Avogadro published a memoria about gas densities, and in 1820 he became the first chair of mathematical physics at the University of Turin.
According to Avogadro, the molecule of oxygen had split into two atoms in the course of forming water vapor.
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.
Eventually proven correct, this hypothesis became known as Avogadro’s law, a fundamental law of gases.
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 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). Avogadro succeeded to his father’s title, earned degrees in law, and began to practice as an ecclesiastical lawyer. After obtaining his formal degrees, he took private lessons in mathematics and sciences, including chemistry. For much of his career as a chemist he held the chair of physical chemistry at the University of Turin.
