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-
