The solubility of N2 in blood can be a serious problem (the "bends") for divers breathing compressed air (78% N2 by volume) at depths greater than 50 ft. Find the volume (in mL) of N2, measured at 25degrees celsius and 1.00 atm, released per liter of blood when a diver at a depth 50 ft rises to the surface. the total pressure (water weight plus atmospheric pressure) on the diver at 50 ft is 2.47535atm (kH for N2 in water at 25 degrees celsius is 7.0x10^-4 mol/Lxatm I got the answer wrong so it said: "you need to use the relationship between solubility and gas pressure, solubility= kh x P to determine the solubility of N2 at the surface and at a depth of 50 ft. You then need to convert the difference in solubility at the two depths to determine the number of moles of N2 released while rising to the surface." it is not .00771 or 17.126 mL which were the two common answers people got.
