The law of conservation of mass states that the total mass of the reactants in a chemical equation must equal the total mass of the products.
Explanation: The law of conservation of mass is a fundamental concept in chemistry that states that matter cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants and products must always be equal, unless energy is present to cause mass change such as in radioactivity.
