Answer 2

$\huge\mathfrak{Answer:}$

It was the great French chemist Antoine Lavoisier in 1789 who proposed the law of conservation of mass.

Law of conservation of mass states that matter cannot be created nor destroyed; there are no more atoms at the end of a chemical reaction than there were at the beginning.
