Law of Conservation of mass

The Law of Conservation of Mass states that in any closed system the amount of mass will remain constant over time. This means that matter can neither be created nor destroyed.

In a chemical reaction, the mass of the reactants you start with will equal the mass of the products once the reaction is complete. Even when matter is transformed, the mass will remain constant.
