Diffusion Rate Calculator

Formula

The formula to calculate the diffusion rate is:

$\text{R2} = \frac{\text{R1}}{\sqrt{\frac{\text{M2}}{\text{M1}}}}$

Where:

$\text{R2}$ is the diffusion rate of gas 2
$\text{R1}$ is the diffusion rate of gas 1
$\text{M2}$ is the molar mass of gas 2
$\text{M1}$ is the molar mass of gas 1

Example Calculation

Let's consider an example:

Diffusion Rate of Gas 1 (R1): 1.5
Molar Mass of Gas 1 (M1): 32 g/mol
Molar Mass of Gas 2 (M2): 28 g/mol

Using the formula to calculate the diffusion rate of gas 2:

$\text{R2} = \frac{1.5}{\sqrt{\frac{28}{32}}} \approx \frac{1.5}{0.935} \approx 1.60$

This demonstrates that with a diffusion rate of 1.5 for gas 1, a molar mass of 32 g/mol for gas 1, and a molar mass of 28 g/mol for gas 2, the diffusion rate of gas 2 is approximately 1.60. ✅
