The answer is helium 0.09 kg/m³.
The wave will move faster in the gas that is having lowest density.
As comparison to other gases-hydrogen, oxygen and radon; helium has the lowest density that is 0.09 kg/m³.
So, waves will move fastest in helium gas as it is having lowest density.
So the answer is helium gas that is waves will move fastest in helium gas.
Hydrogen bonds or covalent but I’m sure it’s hydrogen
