Naproxen is a commercially significant anti-inflammatory agent that can be isolated from the thyroid gland. A solution of 1.138 g of naproxen in 25.00 g benzene has an osmotic pressure of 4.00atm at 20°C. The density of benzene is 0.8787 g/mL at this temperature. Compute the molar mass of naproxen presuming it is a nonelectrolyte as well as the density of the solution equals the density of pure benzene.
