Imagine that the atmosphere is made up of only nitrogen, oxygen, and carbon dioxide. Given that the partial pressures of the three gases is 597.4 mmHg, 158.8 mmHg, and 0.3 mmHg respectively, what is the total atmospheric pressure?
A) 750 mmHg
B) 756.5 mmHg
C) 760 mmHg
D) 765.5 mmHg
E) 770 mmHg

Question

Quizplus · Accepted Answer

The total atmospheric pressure can be calculated by adding the partial pressures of all the gases present. Therefore, 597.4 mmHg (nitrogen) + 158.8 mmHg (oxygen) + 0.3 mmHg (carbon dioxide) = 756.5 mmHg.
