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?
