Oxygen concentration in water (1 Viewer)

Um.... i dont know how this works.. im hoping someone can explain it to me... in my notes i have......... 21% oxygen concentration in atmoshpere... relative percentage in water is 36%.... it then has an explanattion and says there is a much lower oxygen concentration in water than in air.. oxygen is only slighyl soluble in water..

it is correct that potentially, oxygen doesn't dissolve very well in water... troposphere does contain 21% oxygen (78% nitrogen and 1% argon if any one's interested)

i'm not entirely sure what the 36% is all about... perhaps amongst all gases dissolved, oxygen occupy 36%?!?!
