Partial Pressure Calculator

Partial Pressure Calculator

Calculate the partial pressure of a gas from its mole fraction and the total pressure.

* Enter the mole fraction as a decimal (e.g., 0.21 for 21%).

Step 1: Enter Your Data

Enter the total pressure of the gas mixture in atm

Enter the mole fraction of the gas (as a decimal)

Conversion Formula:

$$ P_i = X_i \times P_{\text{total}} $$
where \(X_i\) is the mole fraction and \(P_{\text{total}}\) is the total pressure.
