4. You use a volumetric pipette to take 10 mL of a stock
solution of KMnO and add water to make a more dilute
solution in a 100 mL volumetric flask. Is there more
potassium permanganate in the volumetric pipette or
the 100 mL of solution? Justify your answer

You draw 10 mL of the KMnO4 solution into the pipette and transfer all of it to a 100 mL volumetric flask. Now the flask contains what was in the pipette, no more, no less. The concentration in the flask, because it is diluted, is smaller by a factor or 10 (100 mL/10 mL) but the amount of KMnO4 is the same.
