5. Dextromethorpham, an active ingredient in cough syrups can be determined by fluorescence spectroscopy. A 5.00 mL sample of cought syrup is first diluted to 100.0 mL. A 2.00 mL aliquot of this solution is then diluted to 100.0 mL with distilled water and the fluorescence is recorded as 158. A second 2.00 mL aliquot is combined with 3.00 mL of a standard containing 80.0 ppm of dextromethorpham and the mixture is again diluted to 100.0 ml. This gives a fluorescence reading of 353. Assuming a linear response and zero background, determine the number of miligrams of dextromethorpham in one dose (15 mL) of the cough syrup.
