What is the atmospheric pressure if the partial pressures of nitrogen, oxygen, and argon are 77.75 kPa, 19.94 kPa, and 1.99 kPa, respectively?
This question is testing your knowledge of two things.
1) What gases make up the atmosphere?
2) How does one determine the total pressure of a mixture of gases?
So what are the three most common gases in the atmosphere? They ...
This solution explains how to determine the atmospheric pressure of a mixture of gases by applying Dalton's Law of partial pressures.
