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.
