    Class 11 Chemistry Revision Notes for Chapter 1 - Some Basic Concepts of Chemistry

    Law of Definite Proportions or Law of Constant Composition: This law was proposed by Louis Proust in , which states that: 'A chemical compound always consists of the same elements combined together in the same ratio, irrespective of the method of preparation or the source from where it is taken'.

    Law of Multiple Proportions Proposed by Dalton in , this law states that:' When two elements combine to form two or more compounds, then the differe nt masses of one element, which combine with a fixed mass of the other, bear a simple ratio to one another'. According to this law when gases combine or are produced in a chemical reaction they do so in a simple ratio by volume provided all gases are at same temperature and pressure.

    Molecules are classified as homoatomic and heteroatomic. Homoatomic molecules are made up of the atoms of the same element and heteroatomic molecules are made up of the atoms of the different element have different atomicity number of atoms in a molecule of an element like monoatomic, diatomic, triatomic and polyatomic.

    Atomic Mass Unit One atomic mass unit is defined as a mass exactly equal to one twelfth the mass of one carbon atom.

    Atomic Mass Atomic mass of an element is defined as the average relative mass of an atom of an element as compared to the mass of an atom of carbon taken as Gram Atomic Mass The quantity of an element whose mass in grams is numerically equal to its atomic mass. In simple terms, atomic mass of an element expressed in grams is the gram atomic mass or gram atom.

    Therefore the molecular mass of CO2 is 44 amu.

    It is obtained by adding the atomic masses of all the atoms present in one molecule. Gram Molecular Mass A quantity of substance whose mass in grams is numerically equal to its molecular mass is called gram molecular mass. In simple terms, molecular mass of a substance expressed in grams is called gram molecular mass.

    It is used for the ionic compounds.
