The osmotic pressure of an aqueous solution of a certain protein was measured to determine the protein’s molar mass. Thesolution contained 3.50 mg of protein dissolved in sufficient water to form 5.00 mL of solution. The osmotic pressure of thesolution at 25 °C was found to be 1.54 torr. Treating the protein as a nonelectrolyte, calculate its molar mass.
