One way to make a set of solutions of regularly decreasing concentrations is to make serial dilutions of the most concentrated one. a. starting with a 1.000 M solution, calculate the concentration of the solution prepared by taking 25.00 mL of the stock solution and diluting it properly with water in a 100 mL volumetric flask. b. if you repeat this process 6 times, each time using 25.00 mL of the new dilute solution to make 100.00 mL of a more diluted solution, what will be the concentration of your final solution.
