Q. Explain about Conservation of Mass?
Conservation of Mass above two centuries ago chemists established a fundamental law called the law of conservation of mass.
This law states that throughout a chemical reaction mass is neither lost nor gained. In other sense all the matter present at the start of a reaction still exists at the end of the reaction. The law of conservation of mass is able to be stated in mathematical form as follows
Mass reactants = Mass products
