^Which is true. It doesn't matter if hydrogen or oxium is lighter than air, they still have mass. If I put 1 liter of hydrogen in a balloon, and 100 liters in another balloon with the same volume as the first, which would you expect to float more? floating isn't just dictated by the weight of the material, it works off of displacement too.

If Zephyr and Vauban have roughly the same volume (meaning they displace about the same amount of air), yet one has more mass than the other, which would you expect to float more?
