Solution
The correct option is C
Law of Conservation of Mass was given by Lavoisier in 1774. It can be stated as: “Mass can neither be created nor destroyed during a physical or a chemical change”.According to the law, the mass of the products in a chemical reaction must equal the mass of the reactants.
A given compound always contains exactly the same proportion of elements by weight can be explained by the Law of Constant Proportion. Hence this is an incorrect statement about the Law of Conservation of Mass.
