To make an industrial solvent, benzene (C6H6) is provided at a molar flow rate of 1140 kgmol/hr. Phenol (C6H6O) is also added to the benzene at a rate of 67.25 kgmol/hr to enhance the solvent properties. Finally, it is necessary to add Toluene (C7H8) so that the final solvent production rate (mass flowrate) is 115,000 kg/hr. At what mass flow rate should the Toluene be added?
