The μ rms speed = <u>475,433 m / s
</u>
<h3>
Further explanation
</h3>
Gas particles move randomly (both speed and direction, as vector)
Average velocities of gases can be expressed as root-mean-square velocity. (μ rms)
R = gas constant, 8,314 J / mol K
T = temperature,
K
Mm = molar mass of the gas particles
, Kg
μ rms = root mean square velocity of Gas Particles.,m/s
From this equation shows that the velocity of the gas is inversely proportional to the molar mass of the gas particles
μ ≅ 1 / Mm
So that the greater the molar mass of the gas particles, the smaller the speed (the slowest)
Oxygen gas molecule, O₂ has a molar mass: 0.032 kg / mol
T = 17 °C = 17 + 273 = 290 K
then:
