Can someone clarify to me when we use the units of kJ/mol for delta H versus when we use just kJ for delta H?

They are relatively interchangeable when there is only one mole. But if two mole of the product is formed, if you have it as kj per mole, you would need to multiply your value by 2.

For enthalpy of formation, the convention is to use kJ/mol, but for most other types of enthalpy (enthalpy of a reaction, for example) usually just kJ is okay
