Dalton's Law of Partial Pressures

Dalton's Law of Partial Pressures states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of individual gases. The partial pressure of a single gas in a mixture is the pressure that gas would exert if it occupied the entire volume of the mixture at the same temperature. This principle is widely used in fields such as chemistry and environmental science, assisting in calculations related to the behavior of gas mixtures in various conditions – for example, calculating the amounts of oxygen and nitrogen in breathable air at a certain altitude, or determining the composition of gaseous emissions.
