Law of Conservation of Mass The law of conservation of mass was created in 1789 by a French chemist Antoine Lavoisier The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction For example when wood burns the mass of the soot ashes and gases equals the original mass of the charcoal and the oxygen when it first reacted The conservation of mass is one of the fundamental principles on which modern chemistry is based This page titled 2 5 Conservation of Mass is shared under a CC BY SA 4 0 license and was authored remixed and or curated by Paul R Young ChemistryOnline via source content that was edited to the style and standards of the LibreTexts
