His other contribution includes researches in the field of quantitative chemistry. “Amedeo Carlo Avogadro” Amedeo Carlo Avogardro was born in Italy in 1776 and his main contribution was in the field of relative molecular mass. He established the relationship between the masses of different gasses at the same volume and their corresponding molecular weights. His more noted contribution was the Avogadro law where he established the molar particle number to be exactly equal to 6.022 x 1023

AMEDEO AVOGADRO : 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. He is most noted for his contributions to molecular theory‚ including what is known as Avogadro’s law. In tribute to him‚ the number of elementary entities (atoms‚ molecules‚ ions or other particles) in 1 mole of a substance‚ 6.02214179(30)×1023‚ is known as the Avogadro constant.

system that described the relationship between atoms and elements. Atoms combining into molecules was another discovery found when Gay Lussac saw that the gases produced twice the volume when combining equal volume of different gases. In 1811‚ Amedeo Avogadro realized that the assumptions that gases remain of single atoms to be wrong and that gases actually remain of multiple atoms‚ molecules. The next discovery was the synthesis of urea in the 19th century when Friedrich Woehler synthesized urea from

Two scientists who chose to study this were Amedeo Avogadro and Joseph Louis Gay-Lussac. Amedeo Avogadro had hypothesized that Equal volumes of gases‚ at the same temperature and pressure‚ contain the same number

He was also one of the first chemists who proposed that when in a solution the salt dissociates into ions even in the absence of an electric current. Amedeo Avogadro (1776 - 1856) - He is known for proposing the Avogadro’s Law which states that‚ "Equal volumes of gases contain the equal number of molecules when the given temperature and pressure are same for all the gases."

Becca DeHaven ChemC-125 Avogadro’s Law Experiment Report Introduction: The following experiment’s purpose was to confirm Avogadro’s Law and experimentally determine the Universal Gas Constant “R”. Amedeo Avogadro hypothesized that all gases of equal volume‚ temperature and pressure would contain equal amounts of moles. This idea that volume is directly proportional to moles sprung from other similar hypotheses. Robert Boyle found that pressure and volume are inversely proportional‚ meaning as pressure

JSUNIL TUTORIAL ‚ SAMASTIPUR‚ BIHAR IX CBSE CHAPTR - ATOMS AND MOLECULES The word atom is derived from the Greek word “Atomos” which means indivisible. John Dalton modelled atoms as hard indivisible spheres. An Indian philosopher Maharishi Kanad‚ postulated that if we go on dividing matter (padarth)‚ we shall get smaller and smaller particles. Ultimately‚ a time will come when we shall come across the smallest particles beyond which further division will not be possible. He named these particles
