The vapor density of any material is the molecular weight of the gas/vapor divided by that of air. The molecular weight of air is found by taking a “weighted average” of the molecules found in air. Air is roughly 79% Nitrogen and 21% oxygen. That means, mathematically .79(28) + .21(32). Nitrogen weighs 14, oxygen weighs 16 – but both atoms are diatomic, so they have to be doubled. The final molecular weight of air is approximately 29.

To sum it up, if you divide the MW of a gas by 29, and it’s less than 1 – it floats, greater than 1 it sinks. That should explain the balloons.
