I recently encountered units of energy written as $``\mathrm{kJ}/\mathrm{mol}"$ or $`` \mathrm{kcal} / \mathrm{mol} "$. I'm aware of the meanings of $`` \mathrm{kJ} "$ and $`` \mathrm{mol} " , $ however, I don't understand what they mean when put together like this.

Questions:

1. How does the qualifier $`` / \mathrm{mol} "$ modify the meaning of a unit of energy like $\mathrm{kJ}$ or $\mathrm{kcal}$?

2. Can $\mathrm{kJ}/\mathrm{mol}$ or $\mathrm{kcal} / \mathrm{mol}$ be converted into $\mathrm{kJ}$ or $\mathrm{kcal}$?
