What is the Law of conservation of mass?
The law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction.
This means that new matter is formed from pre-existing matter. We can neither create new matter nor destroy the existing matter.
Examples of law of conservation of mass
– In chemistry
Consider two elements, A and B reacting together to give a compound C. Atoms of elements A and B do not exist individually in the reaction mixture, but come together to give the new compound C.
The mass of compound C is the sum of the masses of the elements A and B.

– In real life
When we make chocolate milk, we mix milk, sugar and chocolate together in a specific quantity. This means that the mass of each ingredient is specified. And the mass of the chocolate milk made from these ingredients will be equal to the sum of the masses of the individual ingredients.
