A 0.200 mol sample of O₂ and 0.600 mol sample of H₂ are placed in a container at 1.20 atm and 25 ° C. What is the partial pressure of H₂ in this container?

Question

Quizplus · Accepted Answer

The total moles of gas are 0.200 + 0.600 = 0.800 moles. The mole fraction of $H_2$ is $\frac{0.600}{0.800} = 0.75$. The partial pressure of $H_2$ is then $0.75 \times 1.20 \, \text{atm} = 0.90 \, \text{atm}$.
