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


Fuel Density at 20o
(g/cm3)
 Molar Enthalpy
 of Combustion
kJ/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.
