v Correct
Part B
How does this compare with AH tor the complete combustion of 1 L of liquid methanol, CH3OH(1)? For
CH3OH(1), the density at 25 °C is 0.792 g/cm, and AH; equals -239 kJ/mol.

Ammonia (NH3) boils at -33° C; at this
temperature it has a density of 0.81 g/cm. The
enthalpy of formation of NH3 (g) is -46.2 kJ/mol,
and the enthalpy of vaporization of NH3 (1) is 23.2
kJ/mol.
