SUMMARY
The translational root mean square (rms) speed of carbon dioxide (CO2) molecules can be determined using the equation V^2 = (3kT)/m, where k is the Boltzmann constant, T is the temperature, and m is the molecular mass. Given that the translational speed of water vapor (H2O) is 648 m/s and both gases are at the same temperature, the ratio V^2/m for H2O and CO2 must be equal. This allows for the calculation of the rms speed of CO2 based on the known speed of H2O.
