Quinine in a 1. 553-g antimalarial tablet was dissolved in sufficient 0. 10 M HCl to give 250 mL of solution. A 10. 00-mL aliquot was then diluted with 50. 00 mL with the acid. The fluorescence intensity for the diluted sample at 347. 5 nm provided a reading of 196 on an arbitrary scale. A standard 100-ppm quinine solution registered 125 when measured under conditions identical to those for the diluted sample. Calculate the mass in milligrams of quinine in the tablet
