The law of conservation of mass states that mass cannot be created or destroyed in a closed system through ordinary chemical reactions or physical changes. This means that the total mass of reactants in a chemical reaction will always equal the total mass of the products. In other words, the amount of matter remains constant, even though it may change forms during reactions. This principle was formulated by Antoine Lavoisier in the late 18th century and is a fundamental concept in chemistry and physics.
