If you use a volumetric pipet to transfer 20 mL of a 0.221 M stock solution into a
100 mL volumetric flask and then filled the flask to the calibration mark with
deionized water, what would the concentration (in M) of the new solution be?
In order to prepare .10 M solution of food dye, how many mL of a 1.62 M stock solution should you add to a 100 mL volumetric flask before filling the flask to the calibration mark?
