Chemists calculate the percent yield of reactions to predict product amount Actual Yield: measured mass of product Theoretical Yield: maximum product mass possible from a given amount of reactant: use stoichiometry Percent Yield AgNO3: 169 9 g/mol Ag2CrO4: 331 7 g/mol 2 2 1 Percent Yield Example In a reaction silver chromate forms when excess
LIMITING REAGENTS THEORETICAL ACTUAL AND PERCENT YIELDS
The theoretical yield is the amount of the product (in g) formed from thelimiting reagent Identify the ACTUAL YIELD: The actual yield is the amount of the product (in g or mol) actually formed inthe laboratory Calculate the PERCENT YIELD: The percent yield is based upon the theoretical yield

Percent Yield “Slaked lime” Ca(OH)2 is produced when water reacts with “quick lime” CaO If you start with 2 400 g of quick lime add excess water and produce 2 060 g of slaked lime what is the percent yield of the reaction? 2060 g = actual yield CaO + H2O Ca(OH) 2 2400 g excess x g = theoretical yield
What is the percent yield?
- 12 g is the theoretical yield 8.25 g is the actual yield. 6. Calculate thePERCENT YIELD: The percent yield is based upon the theoretical yield. actual yield (g) 8.25 g ----------------------- x 100 % = Percent Yield = ---------- x 100 % = 68% theoretical yield (g) 12.16 g
How to calculate the percent yield of a reaction?
- Calculate thePERCENT YIELD: The percent yield is based upon the theoretical yield. actual yield (g) 8.25 g ----------------------- x 100 % = Percent Yield = ---------- x 100 % = 68% theoretical yield (g) 12.16 g (For theoretical yield, carry more sig. figs. in this calculation) Final sig. figs. limited by the given amounts of reactants.
What is the average yield on a Treasury note?
- For example, the six-month U.S. Treasury note now yields more than 5.10%, while one-year Treasuries are yielding more than 5.0%. Two-year U.S. Treasuries yield close to 4.9%, while the three- and five-year notes are at 4.6% and 4.3%, respectively.
What is the difference between theoretical yield and actual yield?
- THEORETICAL YIELD The theoretical yield is the amount of the product in g formed from the limiting reagent. From the moles of limiting reagent available, calculate the grams of product that is theoretically possible (same as Step 4 above). ACTUAL YIELD The actual yield is the amount of the product in g actually formed in the laboratory.
