A 250mL aliquot of an aqueous quinine solution was diluted to 500 mL and found to have an absorbance of 0656 at 348 nm when measured in a 250cm cell A second 250mL aliquot was mixed with

A 25.0-mL aliquot of an aqueous quinine solution was diluted to 50.0 mL and found to have an absorbance of 0.656 at 348 nm when measured in a 2.50-cm cell.

A second 25.0-mL aliquot was mixed with 10.00 mL of a solution containing 25.7 ppm of quinine; after dilution to 50.0 mL, this solution had an absorbance of 0.976 (2.50-cm cell). Calculate the concentration of quinine in parts per million in the sample.
