1. In this experiment, you will make a set of solutions containing different concentrations of crystal violet (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 2.0 x 10-5 M and is dark purple. The diluted solutions will be prepared in cuvettes. 2.0 x 105 M CV* (purple) H₂O V₁ diluted samples of CV* in cuvettes 3.0 mL= V2 Use c₁V₁= C₂V₂ to calculate the volume of the stock 2.0 x 105 M CV+ AND the volume of water to make a 3.0 mL sample of 7.5 x 10-6 M CV+. Show all of your calculations.
