Chemistry

Workers in underwater diving suits necessarily breathe air atgreater than normal pressure. If they are returned to the surfacetoo rapidly, N2, dissolved in their blood at the previously higherpressure, comes out of solution and may cause emboli (gas bubblesin the bloodstream), bends, and decompression sickness. Blood at37âˆ˜C and 1 bar pressure dissolves 1.3 mL of N2 gas (measured forpure N2 at 37âˆ˜C and 1 bar) in 100 mL of blood.
Part A
Calculate the volume of N2 likely to be liberated from the bloodof a diver returned to 1 bar pressure after prolonged exposure toair pressure at 300 m of water (below the surface). The total bloodvolume of the average adult is 4.7 L; air contains 78 vol% N2.
Correct answer from the back of the txtbk is 1800mL .....i just cant figure out how they got it. Thanks

Whne P 1 bar 1 atm and T 37 DegC 37 273 310 K 13 mL of N2 is present in 100 mL of blood Hence the volume of N2 that would be present in 1L 1000 mL of blood 13 mLN2 100 mL blood x 1000 mL blood 1L blood 13 mL N2 See Answer
