Help please. Using the following equation for the combustion of octane, calculate the heat of reaction for 100.0 g of octane. The molar mass of octane is 114.33 g/mole. 2 C8H18 + 25 O2 → 16 CO2 + 18 H2O ΔH°rxn = -11018 kJ

OpenStudy (aaronq):

"ΔH°rxn = -11018 kJ" per mole? convert mass of octane to moles of octane. the heat is given by multiplying the moles of octane by ΔH°rxn
