The osmotic pressure of an aqueous solution of a certain protein was measured in order to determine the protein’s molar mass. The solution contained 3.50-g of protein dissolved in sufficient water to form 5.00-L of solution. The osmotic pressure of the solution at 25oC was found to be 1.54-mmHg. (Hint: Remember to convert mmHg to atm) Calculate the molar mass of the protein.
