Mass & energy balance problem, slightly different question, pls redo

Before entering a combustion chamber, air is heated from 25 C to 150 C. The change in specific enthalpy associated with this process is 3640 J/mol. The flow rate of air at the heater outlet is 1 m3/min, and the air pressure at this point is 122 kPa absolute. Calculate the heat requirement in kW, assuming ideal gas behaviour and that kinetic and potential energy changes from the heater inlet to the outlet are negligible
