1) The first solution is just 50 ml of Crystal Violet (CV) stock solution. It has a concentration of 15 micro Molar. 2) The second solution is 10 ml of deionized water and 10 ml of solution one. 3) The third solution is 10 ml of DI water and 10 ml of solution two 4) The fourth solution is 10 ml of DI water and 10 ml of solution three 5) The fifth solution is 10 ml of DI water and 10 ml of solution four I'm pretty sure we're supposed to use the C1V1=C2V2 formula and solve for C2, but since solutions 2 through 5 are all 2 ml I keep canceling out values and getting the same concentration.
