The degree of polymerization of a certain oligomer sample is described by the distribution function W = K (i

The degree of polymerization of a certain oligomer sample is described by the distribution function W = K (i-i + 5) where w, is the weight fraction of polymer with degree of polymerization i, and i is a continuous variable in the range 1 sis 12. K is a numerical constant. (a) Calculate the number average degree of polymerization. (b) What is the standard deviation of the weight distribution? (Consider problem 3 above) (c) Calculate the z average degree of polymerization. (d) If the formula weight of the repeating unit M, in this oligomer is 100 g/mol, what is M, for the polymer?
