Next, prepare your own “stock” solution from an existing 3.0 x 10-4 M Allura Red solution provided by your instructor. Measure approximately 25 mL of the 3.0 x 10-4 M Allura Red solution in a 100mL beaker, and take it back to your work bench. Take note that the molecular weight of the solute is 496.42 g/mol. The concentration of this solution is well below the solubility limit of the solute so it has readily dissolved to form the solution. From this 25 mL of provided solution, measure 10mL using a 10mL graduated cylinder or 10mL pipette and pour it into a 50 mL volumetric flask. If using a graduated cylinder, you may use a funnel to assist with this. Rinse the graduated cylinder (and funnel if applicaable) with distilled water and add that to the flask as well. Alternatively for a pipette, you can “rinse” the inside of the pipette with additional distilled water as well and add that to the flask. This will ensure all of your solute is transferred. Next add enough distilled water to the flask such that the meniscus of the solution reaches the 50 mL mark. Calculate the molarity of your “new” stock solution, and record it. Label this “Stock Solution.” Additionally, calculate the moles and grams of solute present in the 50 mL sample you just made. This would indicate how much of the pure dye you would have needed in order to make this solution yourself “from scratch.”
