Antoine-Laurent Lavoisier proved it in France in the late 18th century. I'm not sure about any of the specific experiments he used to prove it, but you can go here if you want to read about one experiment at the link below:
He didn't. The name "sulfur" was in use for this substance since the days of the Romans. LaVoisier simply showed that sulfur could not be broken down into any constituent parts, and was thus an "element."
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.
he was executed other scientist belived in old methods therefore it was hard to explain revoulitiners were against him
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 Lavoisier is known to not have any siblings, though other websites may argue differently.

The law of conservation of mass / matter, also known as the law of mass / matter conservation (or the Lomonosov-Lavoisier law), states that the mass of aclosed system of substances will remain constant, regardless of the processes acting inside the system.An equivalent statement is that mattercannot be created nor destroyed, although it may change form. This implies that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products.The law of mass / matter conservation may be considered as an approximate physical law that holds only in the classical sense before the advent of special relativity and quantum mechanics. This historical concept is widely used in many fields such as chemistry, mechanics, and fluid dynamics. However, mass is not conserved in nuclear reactions. The law of conservation of mass was first clearly formulated by Antoine Lavoisier in1789. However, Mikhail Lomonosov(1748) had previously expressed similar ideas and proved them in experiments.
Marie Anne Pierrette Paulze did not receive any specific awards or honors during her lifetime. However, she was known for her significant contributions to the field of chemistry as the wife and research partner of Antoine Lavoisier, a prominent chemist known as the "Father of Modern Chemistry."
LaVoisier was married to Marie-Anne Paulz when he was 28 and she was 13. Their marriage had nothing to do with love or passion -- most marriages between aristocrats at that time were for money or prestigue -- but was a favor that Antoine did for his friend, Jacques Paulz, who wanted to prevent Marie-Anne from marrying someone else. There is no way of knowing if the couple had any intention of having children, or even the extent of passion within their marriage. Either could have been infertile, or they could have viewed their marriage as a legal sham with no intention of consumating it. We can never know.
Antoine-Laurent de Lavoisier (26 August 1743 - 8 May 1794, France)The Law of Mass conservation
Antoine Lavoisier won a prize for figuring out a way to light the streets of Paris, discovered the role oxygen plays in combustion, and received a bachelor degree in college. He worked in geology and chemistry most of his life, and was involved in the French Revolution. -----I wouldn't say the french revolution was an accomplishment. He was beheaded at the guillotine! However, he did have the basic idea of conservation of mass, which contributed to Einstein's E=mc^2. (but that is in many scientist's *opinion*)
He discovered that the phlogiston theory was incorrect, and recognized and named oxygen and hydrogen. He accepted that sulfur is an element, had contributions to metric system, established a list of chemical elements, discovered that diamond is a form of carbon, discovered that water is formed from oxygen and hydrogen, etc. He proposed independently (he had any knowledge of Lomonosov works) the law of mass conservation.
