You have an unknown dye solution whose concentration seems tolie between 0.0006M stock solution and a 0.0004 stock solution.Therefore, you had planned to dilute the 0.0006M stock to createyour calibration standards. However, you see that there is no0.0006M stock left but there is plenty of they 0.0004M stock
a. How could you raise the concentration of some of the 0.0004Mstock to make 75mL of a 0.0006M solution without adding any moredye? Be sure to show calculations and indicate that volume of0.0004M required.
b. Please draw a molecular view picture illustrating the molesof dye remaining constant during this process
