How much energy in kJ is released in burning 2.5 mL of gasoline (assuming that all of it is octane with a density of 0.692 g/mL and a molar mass of 114.23 g/mol)

 

The equation for the combustion reaction is

C8H18(ℓ) + 25/2O2(g) → 8CO2(g) + 9H2O(ℓ)

 

ΔHf° kJ/mol

C8H18(ℓ): -250.3

O2(g): 0

CO2(g): -393.5

H2O(ℓ): -285.8

 
Round your answer to 2 decimal places.
