For a particular isomer of C8H18, the following reaction produces 5113.3 kJ of heat per mole of C8H18(g)

For a particular isomer of C8H18, the following reaction produces 5113.3 kJ of heat per mole of C8H18(g) consumed, under standard conditions.

C8H18 + 25/2(O2) -> 8CO2 + 9H2O
DeltaH= -5113.3 kJ

What is the standard enthalpy of formation of this isomer of C8H18(g)?
