The law of conservation of mass, formulated by Antoine Lavoisier in the 18th century, states that mass is neither created nor destroyed in a chemical reaction. Instead, the mass of the reactants is equal to the mass of the products, meaning mass merely changes form (from reactants to products) but the total amount remains constant.
