Please solve this.

A bulk NMP of styrene is carried out at 125C using styryl-TEMPO alkoxyamine as the mediator. Please calculate the concentration styryl-TEMPO alkoxyamine required to produce polystyrene with a number-average degree of polymerization of 100 at 60% conversion; and the time required for the polymerization to attain this conversion, taking into account the persistent-radical effect. The values at 125C for the parameters required in the kinetics equations are: Rate coefficient for propagation, kp=2500Lmol1s1 Rate coefficient for termination, kt=1.6108Lmol1s1 Equilibrium constant, KNMP=2.51011molL1 Density of styrene =0.85gcm3
