WebFor helium, γ = 5/3 and the molecular mass is .004 kg/mol, so its speed of sound at the same temperature is. v sound in helium = m/s = ft/s = mi/hr. Doing this calculation for air at 0°C gives v sound = 331.39 m/s and at 1°C gives v sound = 332.00 m/s. This leads to a commonly used approximate formula for the sound speed in air: WebStep 1: Molar mass: The mass of 1 mole of a substance is called its molar mass.
