In this experiment you will make a set of solutions containing different concentrations of CV+ by mixing different volumes of a stock CV+ solution with water to give final volumes of 3.0 mL. The stock solution of CV+ has a concentration of 2.0x10^-5M and is dark purple. Use C1V1=C2V2 to calculate the volume of the stock 2.0x10^-5 M CV+ AND the volume of water to make a 3.0 mL sample of 4.0x10^-6 M CV+. Show calculations.

Can someone walk through a few simple algebraic solution-making problems? I know how to use formulas, such as C1V1 = C2V2, however I'm having issues with the conceptual part, mostly for when using two solutes. Problem #1: Make 200 mL of a saline that has 5 mMol NaCl and 15 mMol KCl. Stocks are 0.1 M NaCl & 0.2 M KCl. (and if it's simply the C1V1=C2V2 of one, and then the second, added together in a 200 mL flask...
