Question
Assume that air is 21% $O_2$ and 79% $N_2$ by volume. If the barometric pressure is 740 mm, the partial pressure of $O_2$ is closest to which one of the following [8]
Answer: A
π‘ Solution & Explanation
Partial pressure of $O_2$ = mole fraction of $O_2$ * total pressure = 0.21 * 740 mm = 155.4 mm. [8]
