Workers in underwater diving suits necessarily breathe air at greater than normal pressure. If they are returned to the surface too rapidly, N2, dissolved in their blood at the previously higher pressure, comes out of solution and may cause emboli (gas bubbles in the blood stream), bends, and decompression sickness. Blood at 37 degrees celcius and 1 bar pressure dissolves 1.3mL of N2 gas (measured for pure N2 at 37 degrees celcius and 1 bar) in 100mL of blood.

Calculate the volume of N2 likely to be liberated from the blood when the diver returned to 1 bar pressure after prolonged exposure to air pressure at 300 m of water (below the surface). The total blood volume of the average adult is 4.7 L; air contains 78 vol% N2.
