Which of the following gases is the best choice for inflating a balloon that must remain inflated for a long period of time?

a) argon
b) hydrogen
c) neon
d) oxygen

  • Chemistry -

    The higher the molar mass the more trouble th gas has of getting out of the balloon. The smaller the molar mass.......the easier it is to escape.

  • Chemistry -

    So it's between Argon and Neon right?

    and thank you for helping me

  • Chemistry -

    Why between Ar and Ne? Unless you are just eliminating O and H to concentrate on the other two. On my periodic table, I have the following:
    Ar = about 40
    Ne = about 20
    O = about 32
    H = about 2

  • Chemistry -

    all I know is that Nitrogen and Helium are the one; but these I do not know
