Problem
At identical temperature and pressure, in which of the following gases will sound travel the fastest? a) Nitrogen
(
M
=
28
g mol
−
1
)
(M = 28\,\text{g mol}^{-1})
(
M
=
28
g mol
−
1
)
b) Helium
(
M
=
4
g mol
−
1
)
(M = 4\,\text{g mol}^{-1})
(
M
=
4
g mol
−
1
)
c) Carbon dioxide
(
M
=
44
g mol
−
1
)
(M = 44\,\text{g mol}^{-1})
(
M
=
44
g mol
−
1
)
d) Oxygen
(
M
=
32
g mol
−
1
)
(M = 32\,\text{g mol}^{-1})
(
M
=
32
g mol
−
1
)
