Solving a problem in chemistry section 5 point 91

91. The combustion reaction of benzene is expressed by thermochemical by the equation:
C6H6 (Well) + 71 / 2O2 (g of) = 6SO2 (g of) + ZN2O (g); DH =?
Calculate the the thermal effect of this reaction, if it is known, that the the mole heat of vaporization of benzene is equal to 33.9 kJ.
