• Sulfur hexafluoride - Wikipedia

    The density of sulfur hexafluoride is relatively high at room temperature and pressure due to the gaslarge molar mass. Unlike helium, which has a molar mass of about 4 g/mol and pitches the voice up, SF 6 has a molar mass of about 146 g/mol, and the speed of sound through the gas is about 134 m/s at room temperature, pitching the voice down.
