2.What is the molar enthalpy of formation of propene, C3H6(g) given:

2 \mathrm{C}_{3} \mathrm{H}_{6}(\mathrm{~g})+9 \mathrm{O}_{2}(\mathrm{~g}) \rightarrow 6 \mathrm{CO}_{2}(\mathrm{~g})+6 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \text { delta } \mathrm{H}=-4117.6 \mathrm{~kJ}

\mathrm{C}(\mathrm{s})+\mathrm{O}_{2}(\mathrm{~g})->\mathrm{CO}_{2}(\mathrm{~g}) \text { delta } \mathrm{H}=-393.5 \mathrm{~kJ}

2 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g})->2 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \text { delta } \mathrm{H}=-571.6 \mathrm{~kJ}

(answer in kJ/mol to 1 decimal place)
