find the average molar mass of polyethylene when 4.40 g of the polymer is dissolved in benzene to produce 200.0 mL of solution and the osmotic pressure is found to be7.60 torr ant 25 celcious Degree.

pi = MRT. Remember to convert pi from torr to atm. Solve for M = molarity, then
M = mols/L and solve for mols in the 200 mL. Finally, mols = grams/molar mass. You have mols and grams, solve for molar mass.
