Homework Statement


This is the lab I did: http://chemistry.depaul.edu/wwolbach/205_207/11.pdf
only steps 1,2, & 3 was performed

Homework Equations


MV1=MV2

The Attempt at a Solution



I need help finding the concentration of Ca 2+ and Mg 2+.
I already know the basics of it, but I really don't know how to do this.
My professor explained it badly and they don't really teach you how to do the calculations. Its hard to figure this thing out.

You seem to show some information about your titrant. What information are you using for your SAMPLE? How much volume of analyte solution did you titrate?
 
nevermind I thing I got it
