How many moles of hydrogen and oxygen atoms are contained in 2.0 moles of aluminum acetate, Al(C2H3O2)3?

Consider the heating curve of the generic compound (the illustration is below).   What segment is associated with the enthalpy of vaporization?

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
