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

The correct answer is "Stoichiometry."<br /><br />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.
