Most Probable Speed Calculator

Calculate Most Probable Speed K ±5%

kg/mol ±5%



Formula

The formula to calculate the Most Probable Speed is:

\[ V_p = \sqrt{\frac{2 \cdot R \cdot T_{ga}}{M_{molar}}} \]

Definition

Most probable speed is the speed at the top of the Maxwell-Boltzmann Distribution curve because the largest number of molecules have that speed. Temperature of Gas A is the measure of hotness or coldness of gas A. Molar Mass is the mass of a given substance divided by the amount of substance.

Example Calculation

Let's assume the following values:

Using the formula:

\[ V_p = \sqrt{\frac{2 \cdot R \cdot 45}{0.04401}} = 130.395517711186 \]
