In water saturated air the mole fraction of water vapour is 0.02 . If the total pressure of the saturated air is 1.2 ~atm , the partial pressure of dry air is

Step-by-step solution

Partial pressure of dry air = total pressure mole fraction of dry air array ll p _ dry air & = p _ total _ dry air Given, _ saturated air & =0.02 _ dry air & =1-0.02=0.98 p _ total & =1.2 ~atm p _ dry air & =1.2 ~atm 0.98=1.176 ~atm array
