The following data were obtained by membrane osmometry of solution of a polyethylene sample in xylene at 90 oC. At this temperature the density of xylene is 0.8014 g/ml and that of polyethylene is 0.8173 g/ml. Calculate the molecular weight of the sample. (20 marks)c (g/liter): 2.00 4.00 6.00 8.00p(cm xylene): 3.054 7.32 12.85 19.64Hint: start with converting p/c into m2/s2
