2. In a laboratory experiment 4.567 g of nickel metal was obtained by a student. The student then calculated based on the amount of reactants used that 5.731 g were possible. What is the student's percent yield?
Homework Answers
percent yield = (actual yield/ theoretical yield) *100
percent yield = (4.567/5.731) *100 = 79.6

Assuming the theoretical yield of aspirin for a student's experiment was 3.215 g. Calculate the percent yield of the reaction if the student were to isolate 1.396 g of aspirin. Include the percent to two decimal places.
The Question Is: "A student weighs 0.347 g of KHP on a laboratory balance
The Question Is: "A student weighs 0.347 g of KHP on a laboratory balance. The KHP was titrated with NaOH and the concentration of the NaOH determined to be 0.110 M. For the second titration, the student correctly diluted 6 M HCl from the reagent shelf using a graduated cylinder to obtain approximately 0.6 M HCl. This solution was titrated with the original NaOH solution. The student calculated the concentration of NaOH from the experiment to be 0.099 M. In...
