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.
