Calculate the RMS velocity of chlorine molecules at `15^@C` and 75 cm Hg pressure. (Given : density of `Hg = 13.596 g cm , g = 980.6 " cm " s^(-2)`

Explanation

To calculate the RMS (Root Mean Square) velocity of chlorine molecules at a temperature of 15°C and a pressure of 75 cm Hg, we will follow these steps:

### Step 1: Convert the temperature from Celsius to Kelvin
The formula to convert Celsius to Kelvin is:
\[ T(K) = T(°C) + 273.15 \]

Given:
\[ T = 15°C \]
