wow physic class all over again:aigo: had a head ack for a week after that specal relitivety stuff
that flame was F$#$ing awsome

The balloon would rise because helium is less dense than air, it's not "lighter" - it's less dense.
Assuming that the baloon was just left in outer space by itself with no spaceshuttle around, I'd say it would slowly go towards the closest/largest gravitational mass near it (like a planet or a sun).

A hammer is lighter than air and it doesn't sink in space. The point is that in zero gravity nothing has any "weight" in spite of its mass, therefore a balloon would just hang in the air just the same as a hammer or astronaught.
If the balloon was moved from a vessel containing air into the vacuum of space itself, then the pressure differential between the inside and outside of the ballon would exceed the strength of the latex and it would pop.

Using lighter is correct, 1 gram of helium is and always will be lighter than one gram of nitrogen, where density is mesure of mass per volume, theoretically the balloon ( given that the material of the balloon would only expand minimally and hold a massive amount of pressure) would begin to sink with more and more helium, as its weight being pressurized within the ballon would exceed that of nitrogenous air, here density would in fact be incorect, you cannot describe an element as being dense without a volume.

I was assuming there was a form of gravity, as an air like environment could not exist otherwise, it can however in a low gravitiational environment granted it will be different, thus there is weight as there is a a force acting on the mas of the gassess
I too did not read all of the posts lol. The baloon would do the same thing as a ball of water or even a dude in zero gravity, float in mid-air.

Incorrect..Measured in the same location, 1 gram of helium would NOT be "lighter" than 1 gram of ...anything...nitrogen, lead, feathers, dog shit...its doesnt matter the substance. 1 gram is 1 gram. The volume may be quite different to be sure. And good luck weighing a gram of helium...but thats besides the point
Um...gram....oops...i meant a quantity, reffereing to soemthing like the feather and brick analogy, i think i got a little confused typing.....i guess thank you for clearing that up, sry about the mistyped information ( i was thinking volume in a contained area )
although what you worte is somewhat incorrect also, within different gravtitational fileds a gramwill weigh much less/more than a gram within a different gravitational field ( its mass however will reamin the same of course..)
and weighing gass isnt that hard

If there were no gravity, everything would just fload, the gasses would not be able to separate from eachother. An example is of astronauts not being able to belch because the gas in the stomach cannot be separated in zero grav.

You bodies muscles should be able to forces out any gas from your body regarless of it coming from your mouth or your arse. I can't remember what show it was on, but Steve O was in zero gravity and was able to puke his guts out. If that can be done, then you should be able to burp or fart.
