Below are the values of the osmotic pressure, measured in meters h of a column of manometric liquid, depending on the concentration of the polymer at 25 C:
s, kg/m3 3.201 4.798 5.702 6.898 7.797
h, m 0.0291 0.0583 0.0787 0.1099 0.1397
From these data, determine the molar weight of the polymer and the second virial coefficient. The density of the manometric liquid is 925 kg/m3.
