Amedeo Carlo Avogadro, (/ ˌ ɑː v ə ˈ ɡ ɑː d r oʊ /) Count of Quaregna and Cerreto (9 August 1776 – 9 July 1856), was an Italian scientist, most noted for his contribution to molecular theory now known as Avogadro's law, which states that equal volumes of gases under the same conditions of temperature and pressure will contain equal numbers of molecules.. In tribute to him, the ...


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.


Amedeo Avogadro inherited the title of Count from his father. 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.


In 1811, just three years after John Dalton published his atomic theory , a brilliant theoretician named Amedeo Avogadro proposed his molecular theory.Avogadro's molecular theory related gas densities to molecular weights, explained reacting proportions by volume in terms of molecular ratios and compositions, and suggested methods for determining both molecular weights and compositions.


Amedeo Avogadro was best known for creating Avogadro's Number (or Avogadro's Constant), discovered in 1820. We use this to calculate the results of chemical reactions. This discovery is very important because Avogadro's Number and the mole as a key part of understanding atomic structure. One mole of anything equals 6.022 x 10^23 particles.


…as 1811 the Italian physicist Amedeo Avogadro was able to reconcile Dalton’s atomic theory with Gay-Lussac’s volumetric law by postulating that Dalton’s atoms were indeed compound atoms, or polyatomic. For a number of reasons, one of which involved the recent successes of electrochemistry, Avogadro’s hypothesis was not accepted until ...


Amedeo Avogadro was an Italian Physicist that lived from 1776-1856. He made key discoveries to the molecular theory and helped out many other physicists down the road. Without Avogadro's help, we would have a difficult time understanding moles and atoms.


Avogadro. The flaw in Dalton's theory was corrected in principle in 1811 by Amedeo Avogadro. Avogadro had proposed that equal volumes of any two gases, at equal temperature and pressure, contain equal numbers of molecules (in other words, the mass of a gas's particles does not affect the volume that it occupies).


Amedeo 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.


Avagadro created the basic unit in chemistry, called the mole, which is defined as the number of atoms it takes to make 12 grams of carbon. It is used to compare various substances (atoms and ...
