Root Mean Square Speed allows for the determination of the velocity of 1 type of gas molecule.

Root Mean Square Speed

Concept #1: Root Mean Square Speed

Example #1: Calculate the rms speed of NH3 molecules at 50 ºC.

Practice: Determine which gas would have a root mean square speed of 515.59 m/s at 405 K.

Practice: The root mean square speed of gas molecules is 283.0 m/s at a given temperature T when the recorded molar mass is 42.0 g/mol. What would be the root mean square speed for a gas with a molar mass of 152.0 g/mol?
