Oxygen Partial Pressure Calculator

How to Use the Calculator

1. Enter the total pressure of the gas mixture in atmospheres (atm).
2. Enter the mole fraction of oxygen in the gas mixture.
3. Click the "Calculate" button to compute the partial pressure of oxygen.
4. The result will be displayed in atmospheres (atm).

Working Principle

The partial pressure of oxygen (P_O2) in a gas mixture can be calculated using Dalton's Law of Partial Pressures, which states that the total pressure of a gas mixture is the sum of the partial pressures of its individual components. The partial pressure of a gas is proportional to its mole fraction in the mixture.

The formula used is:

P_O2 = P_total × X_O2

Where:

• P_O2 is the partial pressure of oxygen.
• P_total is the total pressure of the gas mixture.
• X_O2 is the mole fraction of oxygen.
