Kool-aid contains allura red dye. a student makes a kool-aid solution by diluting 61.2 mg of kool-aid with water to a total volume of 25.00 ml using a volumetric flask. because this solution is too concentrated (measured absorbance > 1.0), the student then dilutes a small sample of the kool-aid solution by taking 0.500 ml of the solution and mixing it with 0.500 ml of water (a ½ dilution). the absorbance of the ½ diluted solution is 0.315. using the beer’s law curve, determine the concentration of the dye in the original kool-aid.
