Calculate Molecular Speed



Formula

To calculate molecular speed:

\[ V = \sqrt{\frac{3RT}{M}} \]

Where:

What is Molecular Speed?

Molecular speed is a measure of the average velocity of a group of particles within a gas. According to Kinetic Molecular Theory, all gas particles are in random motion and velocity when their temperature is above 0, so it’s impossible to know any particle’s exact velocity, but the average velocity of all particles can be calculated.

Example Calculation

Let's assume the following values:

Using the formula:

\[ V = \sqrt{\frac{3 \times 8.3145 \times 300}{0.028}} \approx 517.97 \text{ m/s} \]

The molecular speed is approximately 517.97 m/s.
