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

Wouldn't it be = X*P^o where X is the mole fraction of nitrogen. No mass is given but you can assume something convenient like 100 g, calculate the mole N2, O2, and other gases and from that obtain mole fraction nitrogen. Check my thinking.
