What happens to the mass when a solution is formed?

Conservation of mass 10 g 50 g 60 g ? If 10 g of salt is added to 50 g of water, what is the mass of the solution? 10 g 50 g ? 60 g How much salt will be recovered if the mixture is separated by evaporation?

Conservation of mass experiment

Conservation of mass – extension If 10 g of salt is added to 50 g of sea water, what is the mass of the solution? 10 g 50 g ? 60 g How much salt will be recovered if the mixture is separated by evaporation?

The law of conservation of mass states that, in a chemical reaction, the mass of the products always equals the mass of the reactants
