1. A gas X, effuses 0.629 times as fast as O2 (8) under the same condition. What
is the molecular mass of gas X?
2. At what temperature would the root-mean square velocity of the F2 () molecule
equal to the root-mean velocity of the Cl2 (g) molecule at 400.0 K?
3. Compare the rate of effusion of F2 with that of Cl2 under the same
conditions.
