An ideal gas with density of 3.0 g/L has pressure of 675 mmHg at `25^@C` . What is the rms speed of the molecules of this gas?

Explanation

To find the root mean square (RMS) speed of the molecules of the gas, we can use the following steps:

### Step 1: Identify the given data
- Density (D) = 3.0 g/L
- Pressure (P) = 675 mmHg
- Temperature (T) = 25°C

### Step 2: Convert the units
