The solubility of N₂ in blood is a serious problem for divers breathing compressed air (78% N₂ by volume) at depths greater than 50 ft (see the margin note, p. 522). (a) What is the molarity of N₂ in blood at 1.00 atm? (b) What is the molarity of N₂ in blood at a depth of 50. ft? (c) 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 of 50. ft rises to the surface (kH for N₂ in water at 25°C is 7.0X10⁻⁴ mol/Latm and at 37°C is 6.2X10⁻⁴ mol/L atm; assume dof water is 1.00 g/mL).
