The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
EXAMPLE :
... If you massed the reactants oxygen and wax, it would equal the mass of the products water and carbon dioxide.
