let the number of mole of ( mathrm{N} 2 ) dissolved in water be ( mathrm{n} ) Henry's law constant for N 2 at ( 293 mathrm{K} ) is ( 76.48 mathrm{kbar} ). according ti henrys law partial pressure exerted by ( mathrm{N} 2=mathrm{Kh}^{*} mathrm{x} ) ( x ) is the mole fraction mole fraction of ( mathrm{N} 2=x /(mathrm{x}+55.5) ) ( .987=76.48^{*} 10^{wedge} 3^{*} x /(x+55.5) ) ( mathrm{x}=.7 mathrm{milimole} )
