Question

Mass is the amount of matter in something. As per the first postulate of Daltons atomic theory, all matter is made up of atoms. The third postulate of the same theory asserts that atoms can be neither created nor destroyed in a chemical reaction, i.e., the total number of atoms and their mass should remain the same before and after the reaction. This is the same as the law of conservation of mass.how

Solution

Yes both are same.

Antoine Lavoisier's discovery of the Law of Conservation of Mass led to many new findings in the 19th century. Joseph Proust's law of definite proportions and John Dalton's atomic theory branched from the discoveries of Antoine Lavoisier.

The Law of Conservation of Mass states that, in an isolated system, mass is neither created nor destroyed by chemical reactions or physical transformations.

According to the Law of Conservation of Mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

According to Dalton's second law, atoms can neither be created nor destroyed in a chemical reaction which is same as the law of conservation of mass. Hence, Dalton's atomic theory supported the law of conservation of mass.
