calculations involving the mass relationships of elements in compounds matching term Composition Stoichiometry Theoretical Yield Percentage Yield Mole Ratio

The correct answer is "Stoichiometry."Stoichiometry is the branch of chemistry that deals with the mass relationships of elements in compounds. It involves the calculationants and products in a chemical reaction based on the balanced chemical equation. Stoichiometry allows us to determine the proportion of each element in a compound and the amount of each reactant needed or product formed in a chemical reaction.
