Which option correctly distinguishes the law of conservation of mass from the law of definite proportions?

Answer and explanation

Correct answer: Conservation of mass concerns the equality of total reactant and product masses in a chemical reaction; definite proportions concerns the fixed composition of a pure compound

Conservation of mass says that total mass is unchanged during a chemical reaction. The law of definite proportions says that a pure compound has the same elements in a fixed mass ratio, regardless of the sample.
