The law of conservation of mass states is a mass in an isolated system 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 .The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such as amount of gas consumed or produced during a reaction.
