Dalton's Law of Partial Pressure - BYJUS

A mixture of hydrogen gas and oxygen gas exerts a total pressure of 1.5 atm on the walls of its container. If the partial pressure of hydrogen is 1 atm, find the mole fraction of oxygen in the mixture. Applying Dalton’s law formula, P total = P hydrogen + P oxygen. Now, the mole fraction of oxygen, X oxygen = (P oxygen /P total) = 0.5/1.5 = 0.33.
