Answer to Question #118905 in Physical Chemistry for Amanda G

Question

In a reaction, 4.05 mol of product has formed but there are no more visible signs of change. Calculations show that as much as 6.15 mol of product could have formed from the chemical amounts of reactants used. What is the percentage yield?
(Record as 3 digit answer)

Answer 1

Solution: since after the formation of 4.05 moles of the product there are no more visible signs of a reaction, the reaction went to the end. At the same time, theoretical calculations show that 6.15 mol of the product could have formed. Then, the yield is calculated as the ratio of what happened to what could have happened, based on theoretical calculations. Then the output will be: (4.05/6.15)*100%=65.8%.

Answer:65.8%
