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 25

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 25°c 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 2.47535 atm. (kh for n2 in water at 25°c is 7.0 × 10−4 mol/l·atm.)
