Styrene, C8H8, is one of the substances used in the production of synthetic rubber.  When styrene burns in oxygen to form carbon dioxide and liquid water under standard-state conditions at 25°C, 42.62 kJ are released per gram of styrene.  Find the standard enthalpy of formation of styrene at 25°C.
         (Given:  ΔH°f[CO2(g)] = –393.5 kJ/mol, ΔH°f[H2O(l)] = –285.8 kJ/mol, ΔH°f[H2O(g)] = –241.8 kJ/mol)
◦ 147.8 kJ/mol
◦ 323.8 kJ/mol
◦ ~636.7 kJ/mol
◦ ~4249 kJ/mol
◦ ~8730 kJ/mol
