Dalton's Law of Partial Pressure

Definition

Dalton's Law of Partial Pressure states that the total pressure exerted by a mixture of gases is equal to the sum of the pressures that each gas would exert if it were alone.

Partial Pressure:

This refers to the hypothetical pressure of a gas if it alone occupied the entire volume of the original mixture at the same temperature.

Mole Fraction:

Mole fraction represents the number of moles of a component divided by total moles in a solution. It can be used to calculate partial pressure.

Atmospheric Pressure:

Atmospheric pressure is defined as force per unit area exerted against a surface by weight of air above that surface in Earth's atmosphere.
