The osmotic pressure of an aqueous solution of a certain protein was measured to determine the protein's molar mass. The solution contained 3.50 mg of protein dissolved in sufficient water to form 5.00 mL of solution. The osmotic pressure of the solution at 25 Ā°C was found to be 1.54 torr. Treating the protein as a nonelectrolyte (The Van't Hoff Factor = 1), calculate its molar mass.
R = 0.0821 LĀ·atmĀ·molā»Ā¹Ā·Kā»Ā¹
(Note: Don't forget to convert your pressure to atmospheres and temperature to kelvin if you use this version of the gas constant.)
