Law of conservation of mass states that matter can be changed from one form to another,mixtures can be separated or made and pure substances can be decompose but total amount of mass remains constant.
maryamerin:
The law of conservation of mass, or principle of mass conservation, states that for any system closed to all transfers of matter and energy (both of which have mass), the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed. Hence, the quantity of mass is "conserved" over time. The law implies that mass can neither be created nor destroyed, although it may be rearranged in space, or the entities associated with it may be changed i

_________________________________
✴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.
