Calculate the `RMS` velocity of chlorine molecules at `17^(@)C` and `800 mm` pressure.

Explanation

To calculate the RMS (Root Mean Square) velocity of chlorine molecules at 17°C and 800 mm pressure, we can follow these steps:

### Step 1: Identify the formula for RMS velocity
The formula for RMS velocity (\( V_{RMS} \)) is given by:
\[ V_{RMS} = \sqrt{\frac{3RT}{m}} \]
where:
...
