Question
The law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. This means:

Only the number of compounds is conserved
Answer
The total mass of reactants equals the total mass of products
Detailed Explanation
The total mass of the elements present in the reactants must equal the total mass of the elements present in the products, since atoms are neither created nor destroyed.
