Question

Air is about 78.0% nitrogen molecules and 21.0% oxygen molecules. Several other gases make up the remaining 1% of air molecules.
Part A
What is the partial pressure of nitrogen in air at atmospheric pressure (1 atm)? Assume ideal behavior.
Express your answer numerically in atmospheres.

Answer 1

Please help!

Answer 2

the answer may be 0.78 atm

Answer 3

Dalton's Law of Partial Pressure: the pressure exerted by a mixture of gases is equal to the sum of the partial pressures of its components, and the partial pressures are in the same proportions as the nubmer of molecules.
