A standard addition method is used to determine the concentration of ethanol in an
unknown sample. Six 10 mL aliquots of the unknown are drawn from the processing
vat. An aqueous solution of ethanol is standardized to have 1.57 g/L. This standard is
pipetted to five of the aliquots in the following volumes: 5.00 mL, 10.00 mL, 15.00 mL,
20.00 mL, and 25.00 mL. Each of the six solutions is then diluted to a total volume of
50.00 mL.

Is there a question here? Is there any absorbance data here? I don't see either.
