Question

What is the law of conservation of mass?

Answer 1

It states that during a chemical reaction, mass is neither created nor destroyed. Thus, the total mass of the substances before the reaction and the total mass of the substances after the reaction remain the same.

Thus, no mass is lost during the chemical reaction, and the mass is conserved.

Also, for balanced chemical reaction, the total mass of the reactant is equal to the total mass of the product.
