The volume of a gas depends on its temperature and under how much pressure it is.. there is nothing said about that in the question, especially.. what happens after an explosion? The volume would fill the room.

Anyway, if it solved it for you, SiCharlton, than it is all good.
If it's not stated assume STP. You can also assume it's a sealed container, a closed system, and that the final state will also be STP. Just to simplify things. You also have to assume a complete reaction resulting in a single prouct. And the latter is probable the most difficult to justify if this were a real world problem.
