Use the reaction equations and reaction enthalpies to calculate a reaction enthalpy for the combustion of pentane and a molar enthalpy of combustion for pentane.
 
5C(s) +6H2(g) -> C5H12(l)    delta(f)H = -173.5kJ
C(s) + O2(g) -> CO2(g)        delta(f)H = -393.5kJ
H2(g) + 1/2 O2(g) -> H2O(g)   delta(f)H =-241.8kJ
H2O(l) -> H2O(l)                    delta vap H = +40.65kJ

Any help would be appreciated, thanks
