Multiple Choice
Which of the following best describes how to calculate the theoretical yield in a chemical reaction?
A
Calculate the percent yield by dividing actual yield by theoretical yield and multiplying by 100.
B
Measure the actual mass of product obtained from the experiment.
C
Determine the amount of product formed based on the limiting reactant using stoichiometry.
D
Add the masses of all reactants to find the maximum possible product.
Verified step by step guidance1
Understand that the theoretical yield is the maximum amount of product that can be formed from the given amounts of reactants, assuming complete reaction with no losses.
Identify the limiting reactant, which is the reactant that will be completely consumed first and thus limits the amount of product formed.
Use the balanced chemical equation to find the mole ratio between the limiting reactant and the desired product.
Convert the amount of the limiting reactant (usually in moles) to the amount of product using the mole ratio from the balanced equation.
Convert the moles of product to mass (if required) by multiplying by the molar mass of the product to get the theoretical yield.
