Question 7 of 13 > 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 3RT rms speed = where R = 8.314 J/(mol-K) and all is molar mass in kilograms per mole. Note that a joule is the same as a kilogram-meter squared per second squared (kg-m/s2). What is the rms speed of N, molecules at 301 K? m/s rms speed: I What is the rms speed of He atoms at 301 K? rms Speed: m/s
