Gas mixtures and partial pressures | AP Chemistry | Khan Academy


Video Details

For a mixture of ideal gases, the total pressure exerted by the mixture equals the sum of the pressures that each gas would exert on its own. This observation, known as Dalton's law of partial pressures, can be written as follows: P(total) = P₁ + P₂ + P₃ + ... where P₁, P₂, and P₃ are the partial pressures of the different gases in the mixture, and P(total) is the total pressure of the mixture.
