If the translational rms speed of the water vapor molecules (H2O) in air is 647 ms-1, what is the translational rms speed of the carbon dioxide molecules (CO2) in the same air? Both gases are at the same temperature.

[Given: The mass of an H2O molecule = 2.99 × 10-23 g, the mass of a CO2 molecule = 7.31 × 10-26 kg and Boltzmann's constant = 1.38 × 10-23 JK-1 ]
