    Contribution of Amedeo Avogadro to Chemistry Essay (Article)

    Introduction

    Lorenzo Amedeo Avogadro was born in in Turin city of Italy and died in at the age of 81 years after making a great positive contribution in the field of science especially chemistry. He schooled in Turin and having come from a family background of lawyers, his career was oriented towards law whereby at the age of 16 years he had already become a bachelor of jurisprudence and four years down this profession he had managed to get a doctorate in ecclesiastical law which he began to practice and latter in he received an appointment in the department of Eridano as the secretary to the prefecture.

    Amedeo Avogadro

    Italian scientist (–)

    Lorenzo Romano Amedeo Carlo Avogadro, Count of Quaregna and Cerreto[1] (,[2]also,[3][4][5]Italian:[ameˈdɛːoavoˈɡaːdro]; 9 August &#;&#; 9 July ) was an Italianscientist, 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 ratio of the number of elementary entities (atoms, molecules, ions or other particles) in a substance to its amount of substance (the latter having the unit mole), ×1023&#;mol−1, is known as the Avogadro constant. This constant is denoted NA, and is one of the seven defining constants of the SI.

    Avogadro's hypotheses

    Content: gas laws, molar mass

    Level: introductory

    Reference: Amedeo Avogadro, "Essay on a Manner of Determining the Relative Masses of the Elementary Molecules of Bodies, and the Proportions in Which They Enter into These Compounds," Journal de Physique73, ()

    Notes: Amedeo Avogadro's () principal contribution to chemistry was a paper in which he advanced two hypotheses: (1) that lika volumes of gas contain equal numbers of molecules and (2) that elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms. This set of exercises takes students through some of the data Avogadro presented in his paper. They use the atomic model of matter and the concept of a molecular formula that describes molecular composition in terms of definite numbers of atoms of definite mass. They also show how Avogadro's hypotheses made sense of the observations available to him (and to Dalton and Gay-Lussac). Students do not need a modern table of ato
