What would happen to a human if that volume of N2 and O2 were not expelled through the lungs
When scuba diving, it is important to come back to the surface of the water from deep dives slowly. If this does not happen, then the diver can get the “bends”. Using the information provided below, determine the moles of N2 and O2 dissolved in 7.5 L of blood at 298 K at a depth of 100.0 feet below the surface of the water and at the surface of the ocean. If the diver were to suddenly return to the surface, how many moles of N2 and O2 would “undissolve” from the blood (assume no loss of gas molecules from the system)? What volume would this amount of N2 and O2 occupy at the surface of the ocean? What would happen to a human if that volume of N2 and O2 were not expelled through the lungs? Based on your answers, explain why returning to the surface of the ocean after a deep dive is so important, and what the “bends” is. (Henry’s Law constants at 25C K(O2) = 4.40109 Pa, K(N2) = 8.68109 Pa.)
