= Dalton's Law of Partial Pressure =

Dalton's law of partial pressure states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases.

PT = P¹ + P² + P³ PT = the total pressure of the mixture P¹ P² P³ ......... = partial pressures of component gases

Example: PT = P//atm// 731.0 torr PH²O = 17.5 torr P//atm// = PO² + PH²O unknown: PO² in torr

PO² = P//atm// - PH²O you will have to then substitute in values and get: PO² = 731.0 torr - 17.5 torr PO² = 713.5 torr
