The question gives enthalpies of formation in kJ/mol, but then asks for the enthalpy density (enthalpy released per liter). How would I find this? I am given the density of TNT in g/cm^3, but idk how i would use that

[Katie Sy 1L]

to find the energy density in kJ/L, divide the amount of energy with the mass of one mole of TNT(227.14 g/mol) and then multiply it by the density of TNT (1.65 g/cm^3)

[Ian Marquez 2K]

Also, in order to find the energy density per liter, you have to multiply the density which is given by 1.65g/cm^3 by 10^3cm^3/L so your answer and units are correct.
