According to Dalton's law of partial pressures, the total pressure by a mixture of gases is equal to the sum of the partial pressures of each of the constituent gases. The partial pressure is defined as the pressure each gas would exert if it alone occupied the volume of the mixture at the same temperature. The Law of Partial Pressures is commonly applied in looking at the pressure of a closed container of gas and water. The total pressure of this system is the pressure that the gas exerts on the liquid. The gas is made up of whatever sample of gas there is plus the evaporated water. Dalton's law of partial pressures, Pt = P1 + P2 + ..., says that the total pressure of a gas mixture is the sum of the partial pressures of constituent gases. Dalton's law states that the total pressure of a gas is the sum of the individual pressures of all the gas molecules in the container. In other words, it's the average pressure exerted by all the gas particles in a given system.

Final answer:

Dalton's law of partial pressures states that the total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of each component. This law can be expressed mathematically, and is useful for calculating the pressure of specific gases in a mixture.

Step-by-step explanation:

Dalton's Law of Partial Pressures

Dalton's law of partial pressures is a foundational concept in chemistry, particularly when discussing the behavior of gases. The law states that in a given volume and temperature, the total pressure (Ptotal) exerted by a mixture of non-reactive gases is the sum of the partial pressures of each individual gas component. The partial pressure is the pressure that a gas would exert if it were alone in the container. Mathematically, Dalton's law can be represented as Ptotal = P₁ + P₂ + P₃ + ... + Pn, where Pn represents the pressure of each gas within the mixture.

This law is particularly useful when calculating the pressure of a specific gas in a mixture, or when determining the total pressure exerted by a gas mixture. To correct for the vapor pressure due to water, for instance, Dalton's law is used to obtain the true value for the pressure of the rest of the gas. It is a critical concept for anyone studying gas behavior in chemistry.
