This observation, known as Dalton's law of partial pressures, can be written as follows:  P (total) = P ₁ + P ₂ + P ₃ + ... where P ₁, P ₂, and P ₃ are the partial pressures of the different gases in the mixture, and P (total) is the total pressure of the mixture.

As a result, we can use the ideal gas law to calculate the partial pressure of each gas in the mixture. Once we know the partial pressures of all of the gases, we can sum them using Dalton's law to find the total pressure of the mixture.
