Two monodisperse polystyrenes are mixed equally by weight and have molecular weights of 39,000 and 292,000, respectively. What is the intrinsic viscosity of the benzene mixture at 25\deg C? The Mark-Houwink constants for the polystyren benzene system at 25\deg C are: K= 9.18 x 10^(-5) d(L)/(g) and a = 0.74: K=
9.18\times 10^(-5)d(L)/(g) ve a=0.74
