what is stated by the law of conservation of mass?

Answer 1

The law of conservation of mass states that in a closed system, the mass is conserved and remains constant throughout any physical or chemical changes that may occur. This means that the total amount of mass before and after any reaction or process must be the same. In other words, mass cannot be created or destroyed, only transferred or transformed from one form to another. This fundamental law helps scientists better understand and describe various physical and chemical processes in nature.
