101. Solving a chemistry problem

Find the heat carried away by the flue gas at atmospheric pressure, if the composition of its components in volume percent is known, the total volume of gas, the flue gas temperature at the exit of the furnace t1 and the ambient temperature t2, molar heat capacities (J / (mol-k) of flue gas components within the specified temperatures are equal:
СP,CO2=44.44 9.04*10-3T – 8.53*105T-2
СP,CO=28.41 4.10*10-3T – 0.46*105T-2
СP,O2=31.46 3.39*10-3T – 3.77*105T-2
СP,N2=27.87 4.27*10-3T.
Take the number of your option from the table. one
