Homework Statement
If the translationa speed of the water vapor molecules (H2O) in ir is 648 m/s, what is the translational rms speed of the carbon dioxide molecules in the same air? Both gases are at the same tmperature.
Homework Equations
V^2 = (3kT)/m
The Attempt at a Solution
I'm not even sure where to begin. I don't understand how knowing the water's speed helps me find the CO2's.
