Verified step by step guidance1
Understand that the law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.
Recall the historical context of chemistry and the scientists who contributed to foundational chemical laws.
Identify Antoine Lavoisier as the scientist who conducted careful experiments demonstrating that the total mass of reactants equals the total mass of products, thus formulating the law of conservation of mass.
Recognize that John Dalton is known for atomic theory, Dmitri Mendeleev for the periodic table, and Robert Boyle for Boyle's law, which are different contributions.
Conclude that Antoine Lavoisier is credited with discovering the law of conservation of mass.
