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.
