Question

Air contains nitrogen, oxygen, argon, and trace gases. Ifthe partial pressure of nitrogen is 592 mm Hg, oxygen is160 mm Hg, argon is 7 mm Hg, and trace gas is 1 mm Hg,what is the atmospheric pressure

Answer 1

760 mmHg

Step-by-step explanation:

Step 1: Given data

• Partial pressure of nitrogen (pN₂): 592 mmHg

• Partial pressure of oxygen (pO₂): 160 mmHg

• Partial pressure of argon (pAr): 7 mmHg

• Partial pressure of the trace gas (pt): 1 mmHg

Step 2: Calculate the atmospheric pressure

Since air is a gaseous mixture, the atmospheric pressure is equal to the sum of the gases that compose it.

P = pN₂ + pO₂ + pAr + pt = 592 mmHg + 160 mmHg + 7 mmHg + 1 mmHg = 760 mmHg
