.The air is a mixture of a number of gases. The major components are oxygen and.nitrogen with approximate proportion of '20 %' is to '79 %' by volume at '298 K'. The water is in equilibrium with air at a pressure of '10 ~atm'. At '298 K' if the Henry's law constants for oxygen and nitrogen at '298 K' are '3.30 xx 10^7 mm' and '6.51 xx' '10^7 mm' respectively, calculate the composition of these gases in water.

Explanation

Partial pressure of oxygen
.p_o_2=20/100 xx 10 xx 2 atm=2 xx 760 mm=1520 nm.
Partial pressure of nitrogen.
