find the rms speed of oxygen molecules in a gas at 300K.

Explanation

To find the root mean square (RMS) speed of oxygen molecules at 300 K, we can follow these steps:

### Step 1: Write down the formula for RMS speed
The formula for the RMS speed (v_rms) of gas molecules is given by:
\[ v_{rms} = \sqrt{\frac{3RT}{M}} \]
where:
