The partial pressure of oxygen in a sample of air is 452 mm Hg and the total pressure is 780 mm Hg. What is the mole fraction of oxygen?
0.203
0.579
2.030
5.790
Correct answer is B
Mole fraction = \(\frac{\text{Partial pressure of component}}{\text{Total pressure of compound}}\)
= \(\frac{452}{780}\)
= 0.579
