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.

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
