The French premiere was given by the Théâtre-Italien in Paris on 10 May 1801 with Teresa Strinasacchi Avogadro as Carolina and Gustavo Lazzarini as Paolino.

This problem was solved by Amedeo Avogadro, who studied the reacting volumes of gases as they formed liquids and solids.

Lorenzo Romano Amedeo Carlo Avogadro di Quaregna e di Cerreto, Count of Quaregna and Cerreto ( 9 August 1776, Turin, Piedmont – 9 July 1856 ) was an Italian savant.

Amedeo Carlo Avogadro was born in Turin, Italy in 1776 to a noble family of Piedmont, Italy.

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.

The greatest problem Avogadro had to resolve was the confusion at that time regarding atoms and molecules.

The value of the Avogadro constant N < sub > A </ sub > was first approximated by Johann Josef Loschmidt who, in 1865, estimated the average diameter of the molecules in air by a method that is equivalent to calculating the number of particles in a given volume of gas.

He recently was revealed to be in the Caribbean, living a luxurious lifestyle off of the millions he inherited from Avogadro.

Although such proponents of the atomic theory as Amedeo Avogadro and Ludwig Boltzmann made great advances in explaining the behavior of gases, this dispute was not finally settled until Jean Perrin's experimental investigation of Einstein's atomic explanation of Brownian motion in the first decade of the 20th century.

Saint Albert Avogadro ( 1149 – September 14, 1214 ) was a canon lawyer who served as Latin Patriarch of Jerusalem from 1204 until his death.

* July 9 – Amedeo Avogadro, Italian chemist ( b. 1776 )

* July 14 – Italian scientist Amedeo Avogadro publishes his memoire about the molecular content of gases.

Italian physicist Amadeo Avogadro had suggested in 1811 that equal volumes of different gases contain equal numbers of molecules.

The number of entities per mole is known as the Avogadro constant, and is determined empirically.

As early as 1805, Gay-Lussac and von Humboldt showed that water is formed of two volumes of hydrogen and one volume of oxygen, and by 1811 Amedeo Avogadro had arrived at the correct interpretation of water's composition, based on what is now called Avogadro's law and the assumption of diatomic elemental molecules.

Boyle ’ s law, Charles ’ law and Avogadro ’ s law could be combined to give a general relation between the volume, pressure, temperature and the number of moles of a particular gas.

By discovering diatomic gases, Avogadro completed the basic atomic theory, allowing the correct molecular formulae of most known compounds — as well as the correct weights of atoms — to be deduced and categorized in a consistent manner.

* September 14 – Albert Avogadro, Latin Patriarch of Jerusalem ( b. 1149 )

In chemistry and physics, the Avogadro constant ( symbols: L, N < sub > A </ sub >) is defined as the ratio of the number of constituent particles N ( usually atoms or molecules ) in a sample to the amount of substance n ( unit mole ) through the relationship N < sub > A </ sub > = N / n.

The Avogadro constant expresses the number of elementary entities per mole of substance and it has the value.

Previous definitions of chemical quantity involved Avogadro's number, a historical term closely related to the Avogadro constant.

Thus, Avogadro's number is a dimensionless quantity and has the numerical value of the Avogadro constant given in base units.

In tribute to him, the number of elementary entities ( atoms, molecules, ions or other particles ) in 1 mole of a substance,, is known as the Avogadro constant.

Well before this, Avogadro had been recalled to the university in Turin in 1833, where he taught for another twenty years.

Avogadro did not actually use the word " atom " as the words " atom " and " molecule " were used almost without difference.

Avogadro is hailed as a founder of the atomic-molecular theory.
