Answer:

D. 331 mm Hg

Explanation:

We can solve this problem by keeping in mind the law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of its components.

In other words:

  • P oxygen + P nitrogen = Total P

We input the given data:

  • 261 mmHg + P nitrogen = 592 mmHg

And calculate the pressure of the nitrogen:

  • P nitrogen = 331 mmHg
