1. 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.
A. What is the rms speed of Cl2 molecules at 505 K?
B. What is the rms speed of He atoms at 505 K?

2. Use the van der Waals equation of state to calculate the pressure of 3.70 mol of H2O at 473 K in a 5.50-L vessel.
Part 2: Use the ideal gas equation to calculate the pressure under the same conditions.

The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed rms speed=√3RTM where R=8.314 J/(mol⋅K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram‑meter squared per second squared (kg·m2/s2). What is the rms speed of Cl2 molecules at 471...
