101. Solving a chemistry problem

404. Muscle fibrils contain a number of protein components involved in the mechanism of their contraction. One of these components, rabbit skeletal muscle protein M-linin, was studied by equilibrium centrifugation at a rotor speed of 6800 rpm and a temperature of 5 C. The protein had a specific partial volume of 0.797 cm3/g; solvent density 1.041 g/cm3. Calculate the molar mass of this protein using the following data on the distribution of protein concentration along the distance from the centrifuge axis:
x, cm 6.950 6.992 7.035 7.069 7.106 7.132
s, g/l 2.027 2.428 2.868 3.307 3.971 4.479
