Atomic Weight




  • The atomic weight of an element is related to C-12. The atomic weight of carbon – 12 is 12u. The atomic weights of remaining elements are determined by IUPAC and IUPAP considering this as standard. The molecular mass of a molecule is obtained by calculation and adding atomic masses of all atoms. The molecular formula of a compound, the masses of the different elements present in molecular mass is determined by determination of percentage of elements present and determining empirical formula.
  • The number of atoms, molecules or any component in any system is expressed with reference to Avogadro constant. This is know as 1 mole. The quantitative study of reactants and products is called stoichiometry.
