Two gases A and B are held at the same temperature. One of the gases is diatomic, and the other is not. It is found that the ratio of the rms speeds of the two gases is:
V(a)/V(b) = 0.8542
Find the most likely composition of A and B. That is, what are the two gases?
For the purpose of this exercise, assume the gases are pure, and are composed of the most common isotope.
