d) If the retention volume for a monodisperse polyethylene oxide (PEO) sample of 60,000 g/mol is 100 ml in water at 25C, what is the molecular weight of a fraction of poly acrylic acid (PAA) at the same elution volume for the same experimental conditions? The Mark-Houwink parameters, for PEO are K = 7.54 x 103 ml/g and a = 0.79. For PAA K = 16.3 x 103 ml/g and a = 0.74
