the 5 concentrations of the standard solutions are: 100, 200, 400, 600 and 750 (M).

In other words: if you are making 25 mL of each standard solution, how much of the 1mM stock solution do you need to dilute to make the standard solutions (with the concentrations given).

Please include equation used.


  • if you can, please also include the volume of dilution (mL) and the concentration of dilution (M) for the 5 standard solutions (or if you know what equation to use).

Thank you!!!

Part C: Determining the Molar Absorgtiviy of KMn04 Scenario: You've been given a 1 mM stock solution of KMn04, however the simulator can only measure KMn04 solutions with concentration below 800 uM. Using the stock solution, you need to make 5 standard solutions that are in the concentration range of 50 — 800 uM. It's up to you what those concentrations are, however, it is best to spread them out evenly.

Imagine you are making 25 mL of each standard solution using a volumetric flask. Determine what volume (in ml) of the 1 mM stock solution you need to dilute to make each of the five standard solutions. Record each of these volumes in the data table.
