If 74.5% of exhaled air is nitrogen, what is the partial pressure of nitrogen in exhaled air. Assume that the total pressure of exhaled air is 760.mm Hg.

The traditional treatmentfor hyperventilation is to have the individual breathe into a paperbag. The purpose is to increase theamount of CO₂ dissolved in the individual'sblood. The partial pressures (in atm) ofthe gases in typical exhaled airare:

P(N₂)= 0.742, P(O₂) = 0.161, and P(H₂O) =0.063. Assume that the totalpressure is 1.00 atm, and calculate the partial pressure (in atm)of CO₂ in exhaledair.

Dry air is 78.1% nitrogen. What is the partial pressure of nitrogen when the atmospheric pressure is 1.01 x 10⁵ N/m²?
