. A student is interested in the concentration of blue dye in his favorite beverage. He knows that spectroscopy can be used to determine the concentration of dye molecules in a solution. After making several solutions of known concentration, the student measured the absorbance of each of the solutions and prepared the following calibration curve.
The student then finds that if 20.0 mL of his favorite beverage is diluted to a volume of 100.0 mL, the diluted solution has an absorbance of 0.730. Determine the concentration of blue dye in the undiluted beverage.
