1 of 4 Watch the video that shows using the dilution method to make a solution of known concentration. Note that while the video shows the use of a beaker, in the lab we typically use a volumetric flask to make the diluted solution. The stock solution of KMnO, has a concentration of 2.6 10-4 M. The pipette has a volume of 10.0 mL. What is the amount of KMnO, delivered to the solution, in moles? mol X resubmit
