Plotting graph of CuSO4 concentration (at each dilution) vs volume of solution

Question

Hi, I really dont understand how to do this. If someone could help me out, Id appreciate it. This is all the info , I couldnt type it all in because its too much and the table is better in picture http://s1076.photobucket.com/user/Hbjoi_Hggo/media/image.jpg1_zpsalfphs4o.jpg.html

Answer 1

You have to determine the number of moles of CuSO4*5H2O used in each experiment. These numbers should be reported in the 3rd and 2nd to last columns since the amount of copper sulfate should remain the same regardless of the concentration.

 

Then, simply divide the moles of CuSO4*5H2O by the total volume (in Liters) after dilution. This will give you  the molarity of the diluted solution. This result goes in the last column.

 

Finally, the initial concentration should just be 0.03846 M for the entire fifth column because withdrawing aliquots of a sample doesn't change the concentration.

 

I hope that helped out.
