The heat of combustion of octane is -5.52E3 kJ/mol. Calculate the energy in kJ produced when 50.0 g of octane is burned in excess oxygen.
Added by Julian N.
Step 1
First, we need to find the number of moles of octane in 50.0 g. To do this, we need the molar mass of octane (C8H18). The molar mass of carbon (C) is 12.01 g/mol, and the molar mass of hydrogen (H) is 1.01 g/mol. So, the molar mass of octane is: Molar mass of Show more…

Using the following equation for the combustion of octane, calculate the heat associated with the combustion of 150.0 g of octane assuming complete combustion. The molar mass of octane is 114.33 g/mole. 2 C8H18 + 25 O2 → 16 CO2 + 18 H2O ΔH°rxn = -11018 kJ -578.2 kJ -903.4 kJ -803.1 kJ -11018 kJ -7228 kJ

The combustion of one mole of liquid octane, $\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{6} \mathrm{CH}_{3}$ produces 5470 $\mathrm{kJ}$ of heat. Calculate how much heat is produced if 1.000 gallon of octane is combusted. See Exercise 3.68 for necessary information about octane.
