Quinine in a 1.664 g antimalarial tablet was dissolved insufficient 0.10 M HCl to give 500 mL of solution . A 20.00 mLaliquot was then diluted to 100.o mL with the acid. The fluorescence intensity for the diluted sample at 347.5 nm provideda reading of 245 on an arbitary sacle . A standard 100 ppm quininesolution registered 125 when measured under conditions identical to those for the diluted sample. Calculate the mass inmilligrams of quinine in the tablet.
