At what partial
pressure oxygen will have a solubility of 0.06 gram per litre in water at 293 Kelvin Henry's law constant of oxygen in water at 303 kelvin is 46.82 k bar assume the density of the solution to the same as that of water

Given:
Solubility of O2 = 0.06 gram/litre
KH = 46.82 kbar
= 46.82 × 103 bar
Mass of 1 L of water = 1000 gm
Mass of solvent = 1000 - 0.06
≈ 1000 gm
No. of moles of water

Mole fraction of O2
![space equals space fraction numerator No. of space moles space of space straight O subscript 2 over denominator moles space of space straight O subscript 2 plus space moles space of space straight H subscript 2 straight O end fraction

We have,
PO2 = KH × ΧO2
= 46.82 × 103 × 6.75 × 10−5
= 3.160 bar
The partial pressure of O2 is 3.16 bar.
