Essay

C₈H₁₈ (114 g/mol, d = 0.69 g/mL) is a good model for gasoline, and C₁₆H₃₄ (226 g/mol, d = 0.85 g/mL) is a good model for diesel fuel. These compounds have enthalpies of combustion of 5,460 kJ/mol and 10,800 kJ/mol, respectively. Calculate the fuel density (kJ/mL) of these compounds, and determine how many times more valuable diesel fuel is in terms of its energy content as measured by fuel density.
