To make an industrial solvent, benzene(C6H6) is provided at a molar flow rate of 1140 kgmol/hr. Toluene (C7H8) is also added to the benzene at a rate of 213 kgmol/hr to enhance the solvent properties. Finally, it is necessary to add phenol(C6H6O) so that the final solvent production rate(mass flow rate) is 115000 kg/hr. At what mas flow rate should the phenol be added?
