You are a chemist and FBI crime scene investigator and find a sealed bag containing a suspicious white substance. The substance turns out to be a powder containing fentanyl (C22H28N2O, 336.470 g/mol) and lactose (C12H22O11) 342.298 g/mol). To find out exactly how much fentanyl was in the bag, you use a 100.0 mL volumetric flask to dissolve 1.000 g of the white powder in water. The osmotic pressure for the solution at laboratory temperature, 21.7 °C, is 538.2 mmHg. What percent of the white powder is fentanyl?
