Assume that you have a stock solution of epinephrine at a concentration of 3 mg/mL. Knowing that the pipette you will use delivers 20 drops/mL, calculate the number of drops of the stock solution that must be added to a smooth muscle bath containing 27 mL of Locke’s solution so that the final concentration of epinephrine in the muscle bath will be 173 µg/mL.
