Theoretical yield is calculated by using:
Correct answer: C. Mass of limiting reactants
- A. Mass of reactants
- B. Moles from a balanced equation
- C. Mass of limiting reactants
- D. Mass of product
Explanation
Theoretical yield is the maximum amount of product that can be formed in a chemical reaction. It is calculated by finding out the limiting reactant (the reactant that is completely used up in a chemical reaction) and then calculating the mass of product formed from the mass of the limiting reactant. Although this can be calculated by using a balanced chemical equation, the more precise answer would be the mass of the limiting reactant.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
