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

The United States nickel contains about 25% nickel metal and 75% copper metal. Could you use the same experimental procedure to determine the percentage of copper metal in a nickel coin that you used for a penny? Why or why not? Describe any modifications to the procedure that would be required. Hint: think about the reactions involved and the complex ions that would be formed. Here's kind of a summary of the procedure if it helps in answering this question:...

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...
