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 kmno4 has a concentration of 2.6 × 10-4 m. the pipette has a volume of 10.0 ml. what is the amount of kmno4 delivered to the solution, in moles
