Question

0.0729g of analgesic powder are taken from an analgesic powder packet weighing 1.1456g. The 0.0729 g sample was dissolved in 50 mL of methanol. 2.5 mL of this 50 mL sample solution were run through a UV spectrophotometer. Through simultaneous equations it was determined that the concentration of Acetylsalicylic acid was 2.44 E-04 and the concentration of caffeine was 1.11484E-05. What are the concentrations of the two analytes (ASA and caffeine) in the original analgesic packet?
