Answer:
mass cannot be created or destroyed, but changed into different forms". So, in a chemical change, the total mass of reactants must equal the total mass of products whatever the physical state of the reactants and products. The law of conservation of mass can also be stated as "no atoms can be lost or made in a chemical reaction", which is why the total mass of products must equal the total mass of reactants you started with. By using this law, together with atomic and formula masses, you can calculate the quantities of reactants and products involved in a reaction and the simplest formula of a compound One consequence of the law of conservation of mass is that In a balanced chemical symbol equation, the total of relative formula masses of the reactants is equal to the total relative formula masses of the products.
