Problem 14-1

A 25.0-mL aliquot of an aqueous quinine solution was diluted to 50.0 mL andfound to have an absorhance of 0.656 at 3-lS nm when measured in a 2.50-cm cell.A second 25.0-mL aliquot was mixed with 10.00 mL of a solution containing25.7 ppm of quinine; after dilution to 50.0 mL. this solution had an absorbanceof 0.976 (2.50-COlcell). Calculate the concentration of quinine in parts per millionin the sample.
