What is the law of conservation of mass?
It states that no atoms are lost or made during a chemical reaction so the mass of the products equals the mass of the reactants.

If the total mass of all the reactants involved in a chemical reaction was 60 grams (g), what will be the total mass of all the products?
60 grams (g) because:
mass of products = mass of reactants
