504. The protein myosin (one of the main components of mammalian muscle tissue) in an aqueous solution has a strong tendency to form aggregates of two molecules - dimers. The table below cites osmotic pressure measurements at 20° C. under conditions that do not prevent aggregation. Calculate the molar mass of the dimer from this data and find the molar mass of myosin by dividing the result by 2.
s, g/l 2.48 2.92 5.44 7.71 10.35 13.92 18.14
π, mm Hg 0.062 0.071 0.157 0.260 0.366 0.584 0.987
