Methyl methacrylate was polymerized at a mass concentration of 200 g/dm3 in toluene using azobisisobutyronitrile (AIBN) as initiator at a mass concentration of 1.64 x 10-2 g/dm3 and a reaction temperature of 60°C. Calculate the initial rate of polymerization and the number average molar mass of poly(methyl methacrylate) formed in the initial stages of the reaction given that the relevant rate coefficients at 60°C are:
