A 2.536 g quinine tablet was dissolved in 0.100 M HCl and diluted to 1.00 L of solution. Dilution of a 25.0 mL aliquot to 100 mL yielded a solution that gave a fluorescence reading at 347.5 nm of 348 arbitrary units. A second 25.0 mL aliquot of the original solution was mixed with 20.0 mL of 50 ppm quinine solution before dilution to 100 mL. The fluorescence intensity of this solution was 425. Calculate the percent quinine in the tablet.
