A saturated solution is made by dissolving 0.327 g of a polypeptide (a substance formed by joining together in a chainlike fashion some number of amino acids) in water to give 1.70 L of solution. The solution has an osmotic pressure of 4.19 torr at 26 °C. What is the approximate molecular mass of the polypeptide?

A solution is made by dissolving 5.61 g of a new polymer in enough water to make 260 mL of solution. At 25.0 oC, the osmotic pressure of the solution is 0.174 atm. What is the molar mass of the polymer in g/mol? (Use the E symbolism. e.g., 3123 would be 3.123E3 with 3 significant figures - i.e., 2 after the decimal point.)
