If the heat produced by the reaction of combustion of 1 mole of ethanol (MMethanol= 07 g/mol) is 1366.8 kJ/mol, ((see the thermochemical equation below, the formula of ethanol is C2H6O), how much heat in kJ is produced by the combustion of 155 g of ethanol at the same conditions? C2H6O(g) + 3O2(g) → 2CO2(g) + 3H2O(g); ∆H°rxn=−1366.8 kJ/mol
