4D.9

The question asks to explore the rocket fuel by calculating its enthalpy density. How do you know 1/4th or 3292 kj/mol of energy will be released per mole of TNT consumed? Where did they get 3292 kj / mol in the solutions manual ?

I havent looked at the textbook for this problem but its most likely related to how the coefficient for TNT in the equation is 4 so if you want the enthalpy in terms of per mol of TNT, you have to divide by 4. When they just give you deltaH or enthalpy for an entire rxn, its the enthalpy for one MOLE OF THE RXN, NOT ONE MOLE OF TNT (again, situational and im guessing its because there was a coefficient of 4 for TNT).
