The law of conservation of massstates that mass in an isolated system 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

But energy can be converted into mass by Einstein Theory of relativity i. e. E=mc^2 and vice versa
So in an isolated system also there must be some loss of mass in form of energy.

✴Law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction.
✴For example first of all we take a solution of Lead Nitrate in water then take its weight. Let it's its weight be x gram.
✴After that we take some sodium chloride solution and weight it, let it be y gram.
✴Then add this solution to the lead nitrate, we will find that a white precipitate is formed.
✴Then we take weight of total solution, we will find that the total weight of the contents is (x + y) gram equal to the total weight of the two solution taken.
✴Hence, it can be said that mass is neither created nor destroyed even during a chemical change only care to be taken is that no material is allowed to escape during the reaction.
