Calculate the percent yield. • Bornite (CuFeS3) is a copper ore used in the production of copper. When heated with oxygen gas pure copper is obtained
PERCENT YIELD is a ratio between actual yieldand theoretical yieldto measure a chemical reaction’s efficiency It can be calculated by using the following equation: = × 1 Suzi McStruggles was in the lab following a procedure and by her calculations she should make 27g of table salt (NaCl) so that she can season her lunch
Percent Yield - Notes & Examples (Reference Handouts) Theoretical Yield – Actual Yield – Percent yield is a ratio between actual yield and theoretical yield to measure a chemical reaction’s efficiency It can be calculated by using the following equation: Yield = For the following problems calculate the percent yield: 1
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
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 is the ratio of actual yield to theoretical yield expressed as a percent Actual yield Yield = X 100Theoretical yield Example: Silver chromate forms when potassium chromate is added to a solution containing 0 500 g of silver nitrate Determine the theoretical yield of silver chromate
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.
