Answer
Ordinary air contains 78% nitrogen, 21% oxygen and 0.01% carbon dioxide. But oxygen is more soluble in water as compared to nitrogen. Hence, the composition of air dissolved is different from ordinary air.
The composition of air dissolved in water is 33% oxygen, 66% nitrogen and 1% carbon dioxide.
