Percent Yield
? Theoretical yield: the maximum amount of product, which is calculated using the balanced equation
? Actual yield: the amount of product obtained when the reaction takes place
Reasons for Percent Yield
? There are many reasons you might not get the expected amount of product from a reaction
? Sources of error, nature of rxn
? Percent Yield measures how much of the expected product you actually get
? If a package of chocolate chips is supposed to make 48 cookies, but you only make 34 cookies out of it, you didn't get 100% yield
Calculating Percent Yield
? Percent Yield Formula Measure it (given in problem)
percent yield = actual yield x 100 theoretical yield
Use Stoichiometry
Percent Yield Problem #1
? What is the percent yield of this reaction if 24.8 g of CaCO3 is heated to give 13.1 g of CaO?
CaCO3 ? CaO + CO2
? To find out how much product should be made:
? Set the problem up like you would a Mass-Mass Stoichiometry Problem
1. Balance The Equation 2. Convert Grams to Moles 3. Complete Mole Ratio 4. Convert Moles to Grams
? Then find % yield using the formula
