Amedeo Avogadro.

Amedeo Avogadro was born on 9th August 1776 in Turin, Italy. He grade to become a lawyer provided later he became interested in skill. In 1800 he began his private studies in science and mathematics. In 1809 he started t all(prenominal)ing science in mellowed school in Vericelli. It was in Vericelli that he produce any his papers regarding masses and densities of gases and formulated the hypothesis which is direct knows as the Avogadro Law. In 1811 Avogadro published an article showing the difference amidst a scrap and an atom. Other scientist homogeneous Dalton had got confused and believed that a molecule and atom are the same. Avogadro clarified that two atoms of gases like enthalpy and oxygen formed one molecule of each gas. Avogadro come along formulated Avogardos Principle which stated that equal volumes of all gases at the same temperature and pressure contain the same consider of molecules. This sway was of great importance. other scientists like Cannizarro used this statement to put atomic weights, molecular weights of various gases and the number of molecules in hero sandwich weights of the gases. Cannizarro also determined the constant number of molecules in bomber weights of the gases to be exactly 6.022 x 1023. This number was called Avogadro subjugate in the honour of the scientist.

Before Avogadros time, the qualitative basis of chemistry was sonorous known just quantitive basis was not clear. For example, it was known that atomic number 17 and hydrogen will react to form hydrochloric acid but it was not clearly known how untold hydrogen was needful to react fully with cert ain amount of chlorine and how ofttimes hyd! rochloric acid will be produced. Avogadros researched helped exact determination of quantities of strange gases which will be required to fully react with each other and also the exact quantity of the new...
