As a note, this is my first post on this site. I was looking at some bouyancy calculations with regard to balloons being in air when I came across this post. I cannot understand why the calculation for the net force of bouyancy done by Vintage (the last post on the page) does not include the volume number in the calculation. Does it have something to do with it being calculated at STP? Should the calculation not inlcude a number for the volume of the balloon? Is there some condition that the volume term can be ignored?
