Solution:

The answer to the riddle is 'a hole.' A hole is weightless and can be seen as an absence of material. When you put a hole in a barrel, it effectively makes the barrel lighter by removing some of its substance.

A void of space?
Nothing?
Nothing is weightless, and nothing will make the barrel lighter. You can put helium which will make the overall weight of the barrel and it's content lighter than the barrel with oxygen, but you will not have made the barrel any lighter.
