Question

In Analytical Chemistry, we are conducting an Absorbance Lab using CuSO4 . 5H2O . In the lab we are conducting a calibration curve and as part of our prelaboratory procedure we are asked to calculate the molarity of dilutions made from a stock solution; however, I am unsure how the crystalline water affects this calculation or if it is simply a straight forward C1V1=C2V2 calculation. I would really appreciate the help!

"Calculate the concentration for each solution that are prepared by the following:

 

                                                                                                                 Molarity (M)                                                                                                                     

2.00 mL of stock diluted to 10.00 mL 

 

4.00 mL of stock diluted to 10.00 mL

 

6.00 mL of stock diluted to 10.00 mL

 

8.00 mL of stock diluted to 10.00 mL 

 

           The stock solution is .1000M CuSO4 5H2O.

Follow-up Question

This is somewhat helpful; however, the stock solution is 0.1M, not 1000M and the final answer should be in M (mol/liter) because we are calculating for concentration?
