The law of conservation of mass is a fundamental principle in chemistry.
The Law in Action: Imagine a closed system, like a sealed test tube during a chemical reaction. This law states that the total mass of the starting materials (reactants) will always be equal to the total mass of the ending materials (products). In other words, no matter how the atoms rearrange during the reaction, the overall mass stays constant.
