What is the Dalton’s Law Calculator?

The Dalton’s Law Calculator estimates the unknown pressure in a gas mixture based on Dalton’s Law of Partial Pressures. By entering the total pressure or the pressures of individual gases, this tool can calculate the missing value in the mixture. It ensures that exactly one value is left blank to perform the calculation and displays the result clearly, helping students, scientists, or enthusiasts verify calculations, plan experiments, or understand gas behavior in mixtures.

How to Use:

1. Enter Total Pressure (P_T): Type in the total pressure of the gas mixture if known. Leave blank if you want the calculator to find it.
2. Enter Gas Pressures (P₁, P₂, P₃): Input the pressures of up to three individual gases. Leave exactly one value blank to calculate it.
3. Click “Calculate”: The calculator computes the missing pressure using Dalton’s Law and displays the result.
4. Review the Result: Use the displayed value to confirm calculations, adjust experimental parameters, or better understand gas mixtures.
