The Quinine in a 1.664 g. antimalerial tablet was dissolved in sufficient 0.1 M HCl to give 500 mL of solution. A 20.00-mL aliquot was then diluted to 100.0 mL with the acid. The fluorescence intensity for the diluted sample at 347.5 nm offers a reading of 245 on an arbitrary scale. A standard 100-ppm quinine solution registered 125 when measured under conditions identical to those for the diluted sample. Compute the mass in milligrams of quinine in the tablet.
