Can someone please explain how to identify whether our answers should result in kj or kj/mol?
Thanks!

You will be using kj most of the time because problems typically ask how much heat is required or released. kJ/mol is the unit used for standard enthalpies, which you can see in the tables throughout the chapter or the appendix. Just think about the question is asking for and see if you need to use kJ/mol and how much substance you have to get an answer in kJ
