Your research director informs you that the molecules of a sample of gas at 397 k have a root‑mean‑square (rms) speed of 275 m/s and asks you to calculate the most probable speed and the average speed. also, while you're at it and before lunch, you should calculate the mass of a molecule.

Explanation:

Hello,

Since the rms speed is defined as:

Whereas is the molecular mass of the gas, we solve for it since it is involved in the mathematical definition of both the most probable (mp) speed and the average speed (a):

(remember that J=kg*m/s^2 that's why the result lies on kg/mol).

Now, the mp speed is computed via:

Finally, the average speed is computed via:

Best regards.
