The concentration of dye in Solution A is 20.286 M. You have 13 mL of water at your disposal to make the dilutions. The solution is diluted twice, to make Solutions B and C. In the first dilution, 5 parts of Solution A is diluted with 12 parts water to make Solution B. In the second dilution, 2 parts of Solution B is diluted with 4 parts water to make Solution C. What is the concentration of dye in Solution C?

Suppose you have 100.00 mL of a solution of a dye and transfer 2.00 mL of the solution to a 100.00 mL volumetric flask. After adding water to the 100.00 mL mark, you take 5.00 mL of that solution and again dilute to 100.00 mL. If you find the dye concentration in the final diluted sample is 0.000129 M, what was the dye concentration in the original solution? Concentration
