What is the Law of Conservation of Mass?

The Law of Conservation of Mass states that the mass of the products in a chemical reaction must be equal to the mass of the reactants. In other words, mass cannot be created or destroyed in a chemical reaction, it can only be rearranged. This law is a fundamental principle in chemistry and is crucial for understanding and predicting the outcomes of chemical reactions. By applying this law, scientists and researchers can better understand the behavior of matter and develop new materials and compounds.
