Scuba divers must be very conscious of Caisson's disease, commonly called 'The Bends'. The air we breathe is composed of 21% oxygen, 78% nitrogen, and <1% other gases. For the following problems, assume the SCUBA diver’s air tank contains air with this same composition and a temperature of 25°C. a. Calculate the solubility of N2(g) in the blood at sea level where the air pressure is 1 atm. (Note: kH, N2 = 6.25 x 10-4 mol/ L×atm.) Assuming N2(g) behaves ideally, what volume does this N2(g) occupy per 1 L of blood? b. As a SCUBA diver goes to greater depths, the pressure increases. At a depth of 40 m, the pressure on a diver is 5 atm. Calculate the concentration of N2(g) in the blood of a diver breathing air at this depth. d. Calculate the total moles of nitrogen gas released from the blood and the volume the N2(g) occupies if a diver with total blood volume of 5.5 L instantaneously returns to the surface.
