The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.

where R=8.314 J/(mol·K) and ? is molar mass in kilograms per mole. Note that a joule is the same as a kg·m2/s2.

1. What is the rms speed of F2 molecules at 475 K?

2. What is the rms speed of He atoms at 475 K?
