We are being asked to determine which of the following fuel will give the most energy per unit volume

 Fuel Density at 20oC (g/cm3) Molar Enthalpy of CombustionkJ/mol Nitroethane, C2 H5 NO2 (l) 1.052 - 1368 Ethanol, C2 H5 OH(l) 0.789 - 1367 Methylhydrazine, CH6 N2 (l) 0.874 - 1305

The unit for energy is kJ and the unit for volume is cm3. So that, energy per unit volume is kJ/cm3.
