P5B.7 The molar mass of a protein was determined by dissolving it in water, and measuring the height, h, of the resulting solution drawn up a capillary tube at 20°C. The following data were obtained. c/(mg cm) 3.221 4.618 5.112 6.722 h/cm 5.746 8.238 9.119 11.990 The osmotic pressure may be calculated from the height of the column as Il=hpg, taking the mass density of the solution as p=1.000 gcm³and the acceleration of free fall as g=9.81 ms. Determine the molar mass of the protein.
