Who is amedeo avogadro di quaregna

Some historians[which? Avogadro held posts dealing with statistics, meteorology, and weights and measures he introduced the metric system into Piedmont and was a member of the Royal Superior Council on Public Instruction. In honor of Avogadro's contributions to molecular theory, the number of molecules in one mole was named Avogadro's number, NA or "Avogadro's constant". It is approximately 6. Avogadro's number is used to compute the results of chemical reactions.

It allows chemists to determine amounts of substances produced in a given reaction to a great degree of accuracy. Johann Josef Loschmidt first calculated the value of Avogadro's number, often referred to as the Loschmidt number in German-speaking countries Loschmidt constant now has another meaning.

This law describes the relationship. Respect that is given to someone who is admired. Respect that you earn from doing or achieving something great. Amedeo Avogadro was an Italian scientist who formulated what is now known as Avogadro's law.

Historians of science have several theories as to why this should be so, as Avogadro was a respected scientist during his life. One possibility was that a more famous scientist, J. Berzelius, was strongly advocating his "dualism" theory which explained compound substances molecules? It was hard to see how two atoms of oxygen in one of Avogadro's "molecules" could have different charges.

But the real reason is probably more prosaic. In the clannish world of scientific discovery, it pays to be at the center of the action. Avogadro was by this time a professor, and chairman, of physical chemistry at the University of Turin, but in Italy - far away from the major science centers of England, Germany, France or even Sweden. He never got to rub shoulders with the "great ones" of his day, so his ideas did not receive the credit they deserved.
