An unknown gas has a density of 0.146 kg/m3, and air has a density of 1.275 kg/m3.?

If a balloon is filled with 0.252 m3 of helium, what is the maximum mass the balloon can have and still float?

    makes no sense. You have three gases listed, unknown, air, and helium, plus water. which is in the balloon, which is around it, and how does the water fit in??

      are you sure you are listing the questions EXACTLY as you have them.

      I've found that that is frequently the area of misunderstanding. It just takes one word misstyped to cause this. ??

      for example, I suspect those are actually m³, not m3.

    I'm a total non-scientist, but doesn't this also depend on the density and mass of the balloon, and the density of the water. How does the unknown gas fit into this question?
