Chemical Arithmetic and Chemical Stoichiometry

Chemical Arithmetic

Chemical Arithmetic and Chemical StoichiometryChemistry is mainly an experimental science, in which we study about physical properties and chemical properties of different substances and measure these properties up to highest possibility with great efforts to get results with great precision and accuracy. Results of our experimental measurements or numerical problems have-
  • Arithmetic number,
  • Unit of measurement.

Chemical Stoichiometry

Chemical stoichiometry is all about the calculation or measurement of relative quantities of the reactants and products involved in any chemical reaction. Stoichiometry utilizes the Law of Conservation of Mass or Principle of Mass Conservation so according to law of conservation of mass, "Matter is neither created nor destroyed". Which means in a chemical reaction, amount of elements remains same in starting when only reactants there and at the completion of the reaction when product formed. We always use the “Law of conservation of mass” when we balance chemical equations. 
Stoichiometry is further divided into two branches, which are-
In Stoichiometry calculations we used different formulas and rules like-
