The partial pressure of a gas is perhaps a measurement of the thermodynamic activity of the gas's molecules.

Partial pressure=Total pressure of gases × Mole fraction of a gas

The partial pressure of a gas is derived by multiplying the mole fraction by the total pressure.

The mole fraction of a mixture is the ratio of the number of moles of one component to the total number of moles of all components. The partial pressure of a gas in a gas mixture may be estimated by multiplying the gas's mole fraction by the total pressure. The mole fraction is computed by dividing the number of moles of the gas by the total number of moles of the mixture's components.

The partial pressure of a gas is the pressure that it will release if it is the only gas existing in the container. Different gas laws can be used to describe the characteristics of gases. One of these is Dalton's law of partial pressures. This law states that the total pressure of a gas mixture is equal to the sum of the partial pressures of the component gases.
