It is OK to use your textbook, but if you can answers the questions without it that is OK too.

Do not press the RETURN or ENTER key while you are answering these questions. Your browser will interpret either the same as clicking on the Submit key.

Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.


First Name:

Last Name:

School:

 

 

Solution formation: By dilution.

Watch the movie to see how to prepare 250 mL of a 0.100 M CuSO4 solution from a more concentrated 1.00 M CuSO4 solution.

 

 

1. After watching the movie at the beginning of the BCE describe how would you prepare 500 mLs of a 0.750 M NaCl solution from a 3.75 M NaCl solution.

2. How many moles of NaCl are contained in 500. mLs of a 0.750 M solution? moles

3. What volume of a 3.75 M NaCl solution contains 4.50 mol NaCl? liters

4. Calculate the number of mol of HCl in a 250 mL sample of 3.00 M HCl. mol

5. Calculate the number of mol of Mg in 1.60 g Mg solid. mol

6. Write a balanced chemical equation to describe the reaction that will occur when 1.60 g Mg solid is added to 250 mL of 3.00 M HCl.

7. Calculate the mass of the gaseous product formed when the reation in Q6 is complete. grams

8. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

9. If there is one question you would like to have answered in lecture, what would that question be?
