This should be simple but I'm just not figuring it out :/
Chemical X has a concentration of 2000 U/mL. Chemical Y has a fixed volume of 100 uL and cannot be increased or decreased in the final volume. I want a final solution with a concentration of 2 U/mL.
I naturally tend to think this could be solved by simply doing C1V1 = C2(V2 + V1), however I notice this equation will asymptotically approach infinity if your initial concentrations are similar, which means it's probably not a proper equation. So how do I figure out how much of Chemical X to add to Y to achieve my desired concentration, while taking into account the volume of X that's being introduced? Or might I be thinking of this the wrong way entirely?
