The law of conservation of mass was formulated by the French scientist Antoine Lavoisier in 1789. He demonstrated that in a closed system, the total mass remains constant in a chemical reaction, even if the substances change form.
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. ... If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
Antoine-Laurent de Lavoisier's Traite Elementaire de Chimie from 1789 (Elementary Treatise of Chemistry in English) is considered the basis of the Periodic Table of the elements. The textbook contained a list of elements classified as metals and nonmetals.

Antoine Lavoisier, in 1789.
The law of conservation of mass was formulated by the French scientist Antoine Lavoisier in 1789. He demonstrated that in a closed system, the total mass remains constant in a chemical reaction, even if the substances change form.
The law of conservation of mass states that in an isolated system, energy is neither created nor destroyed. It was first described by Antoine Lavoisier in 1789 and was later amended by Einstein in the Law of Conservation of Mass-Energy.

The earliest known first use of Carbon is 3750 BC. by the Egyptians and Sumerians but the first true chemical analyses was in 1789 by Antoine Lavoisier as an element.
Antoine Lavoisier published the first list of elements in 1789 in his book "Traité élémentaire de chimie" (Elementary Treatise of Chemistry).
This theory was made in 1807 by John Dalton.
The law of conservation of mass (matter is neither created nor destroyed) was first clearly formulated by Antoine Lavoisier in 1789. However, Mikhail Lomonosov (1748) had previously expressed similar ideas and proved them in experiments.
Antoine Lavoisier is often credited with writing the first modern chemical textbook, titled "Traité élémentaire de chimie" (Elementary Treatise of Chemistry), published in 1789. This work laid the foundation for modern chemistry by introducing the concept of elements and identifying oxygen as a key component in combustion.
