Partial Pressure Calculator
Effortlessly calculate partial pressures of gases using this easy-to-use widget.
What is the Partial Pressure Calculator & How does it work?
Partial pressure is the pressure exerted by a gas in a mixture, assuming ideal behavior. It can be calculated using Dalton’s Law of Partial Pressures, which states that the total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas.
The formula for partial pressure is given by:This calculator allows you to input the mole fraction and total pressure to determine the partial pressure of a specific gas in the mixture.
The formula for partial pressure is given by:
P_i = X_i \times P_{total}
Pi = Partial Pressure of gas i
Xi = Mole fraction of gas i
Ptotal = Total pressure of the mixture
Xi = Mole fraction of gas i
Ptotal = Total pressure of the mixture
Parameters
Partial Pressure (Pi) in atm—
