Stoichiometry is based on the law?
...Stoichiometry is based on the law?
multiple proportion
constant composition
conservation of energy
conservation of mass
Correct answer is D
The principles of stoichiometry are based upon the law of conservation of mass. Matter can neither be created nor destroyed, so the mass of every element present in the product(s) of a chemical reaction must be equal to the mass of each and every element present in the reactant(s).
