Calculate the root mean square velocity of nitrogen at `27^(@)C` and `70cm` pressure. The density of `Hg` is `13.6 g cm^(-3)`.

Explanation

To calculate the root mean square velocity (Vrms) of nitrogen (N2) at 27°C and 70 cm pressure, we will follow these steps:

### Step 1: Convert the temperature from Celsius to Kelvin
The formula to convert Celsius to Kelvin is:
\[ T(K) = T(°C) + 273.15 \]
For 27°C:
\[ T = 27 + 273.15 = 300.15 \, K \]
For simplicity, we can round this to 300 K.
