Calculate the rms velocity of oxygen molecules at S.T.P. The molecular weight of oxygen is 32.

Explanation

To calculate the root mean square (rms) velocity of oxygen molecules at standard temperature and pressure (S.T.P.), we can follow these steps:

### Step 1: Understand the Formula
The formula for the root mean square velocity (Vrms) is given by:
\[ V_{rms} = \sqrt{\frac{3RT}{M}} \]
where:
