A mixture of H₂ and O₂ is placed in a 5.00 L flask at 22 °C.The partial pressure of the H₂ is 2.7 atm and the partial pressure of the O₂ is 1.5 atm.What is the mole fraction of H₂?

Question

Quizplus · Accepted Answer

The mole fraction of a component in a mixture is calculated by dividing the partial pressure of that component by the total pressure of the mixture. Here, the total pressure is 2.7 atm (HS) + 1.5 atm (O) = 4.2 atm. The mole fraction of HS is 2.7 atm / 4.2 atm = 0.642857, which rounds to 0.64.
