The osmotic pressure of a solution of a synthetic polyisobutylene in benzene was determined at 25 °C. A sample containing 0.30 g of solute per 125 mL of solution developed a rise of 3.4 mm at osmotic equilibrium. The density of the solution was 0.88 g/mL. What is the molar mass of the polyisobutylene?
chemistry help please!!! very important! due in 20 minutes!?
