Dalton's law

Dalton's law of partial pressures states that the pressure of a mixture of gases simply is the sum of the partial pressures of the individual components.

Dalton's Law is as follows:

 P_Total = P₁ + P₂ + P₃ + ... +P_n =  ∑ Pi where i = 1 to n

OR

 P_Total = P_Gas + P_H2O

where P_Total is the total pressure of the atmosphere, P_Gas is the pressure of the gas mixture in the atmosphere, and P_H2O is the water pressure at that temperature.
