Question

At what partial pressure, oxygen will have a solubility of $0.06g{L}^{-1}$ in water at 293K? Henry's law constant ($K_H$) of $O_2$ in water at 303 K is 46.82 k bar. (Assume the density of the solution to be the same as that of water)

Answer 1

Solubility of oxygen $=$ 0.06 g/L

$K_H$ $=46.82$ kbar

P=$K_H\times \left(x\right)=\left(46.82\right)\times 0.06=2.81$ bar

Partial pressure $=2.81$ bar
