<center>Dalton's Law of Partial Pressure (Mixture of Gases)</center>
 
Sometimes, a container can hold a mixture of gases and not just one gas. As you know from the KineticTheoryofGas (and ideal gas law) that each gas thinks it is alone in the container. Therefore, each gas occupies the total volume of the container and exerts its own pressure called partial pressure (Pi where i = each gas.

The total pressure of the gas mixture is the summation of the partial pressure of all the gases in the container or Ptotal = P1 + P2 + P3 (have 3 gas species in mixture.
