Presentation transcript:

Percent Yield You prepared cookie dough to make 5 dozen cookies. The phone rings while a sheet of 12 cookies is baking. You talk too long and the cookies burn. You throw them out (or give them to your dog.) The rest of the cookies are okay. How many cookies could you have made (theoretical yield)? How many cookies did you actually make to eat? (Actual yield) 28

Vocabulary Actual yield is the amount of product actually recovered from an experiment Theoretical (possible) yield is the maximum of product that could be produced from the reactant. Percent Yield is the actual yield compared to the maximum (theoretical yield) possible. 29

Percent Yield Calculation What is the percent yield of cookies? Actual Yield (g) recovered Possible Yield (g) Percent Yield = X 100 48 cookies 60 cookies % cookie yield = = x 100 80% yield 30

Example. Determine the percent yield for the reaction between 2 Example Determine the percent yield for the reaction between 2.80 g Al(NO3)3 and excess NaOH if 0.966 g Al(OH)3 is recovered

A piece of copper (II) with a mass of 5 A piece of copper (II) with a mass of 5.00 g is placed in a solution containing 15.00 g silver (I) nitrate. The actual silver metal produced has a mass of 5.2 g. Write and Balance Chemical Equation: limiting reactant._____________ excess reactant: _____________ How much excess is remaining What is the percent yield for this reaction.
