Final concentrations unknown volume

  1. Jul 28, 2012 #1
    I have a known volume of water with a known concentration of calcium.
    I want to bring that volume up to a new (slightly) higher volume with a new (slightly) higher concentration. To do this I am adding a solution with a known concentration of Ca but cannot remember how to calculate the volume (of the second solution) I need to get to the final concentration. I cannot adjust the concentration of the second substance, I can only adjust the volume.

    Use the equation: C1V1 = C2V2
