Yup, that's the correct answer AND correct units ;)
Now of course there is the issue of significant figures.
If I were answering that question, I would just use 2.0kJ, or perhaps 2.08kJ, keepint it to 2 or 3 significant figures.
But if you haven't covered anything like that yet, just leave it as what you have said above.
Or use both.
Or, if you are now confused, just ignore me!
aight then thanx alot
