what volume of fuel should you bring? assume each of the following: the fuel has an average formula of c7h16; c 7 h 16 ; 15% % of the heat generated from combustion goes to heat the water (the rest is lost to the surroundings); the density of the fuel is 0.78 g/ml; g / m l ; the initial temperature of the water is 25.0 ∘c; ∘ c ; and the standard enthalpy of formation of c7h16 c 7 h 16 is -224.4 kj/mol k j / m o l .
