A gas 'X' is present with saturated water vapour over water liquid at total pressure of 1.5 atm. Vapour pressure of `H_2O` at same temperature is 0.5 atm. What is the solubility of gas 'X' in terms of moles in 10 moles `H_2O`. The slope of the graph is 5000.

A vessel has nitrogen gas and water vapour in equilibrium with liquid water at a total pressure of 1 atm. The partial pressure of water vapours is 0.3 atm. The volume of this vessel is reduced to one third of the original volume, at the same temperature, then total pressure of the system is: (Neglect volume occupied by liquid water)

The volume of 0.5 mole of gas at 1 atm pressure and 273^(@)C temperature is

A vessel has nitrogen gas and water vapours at a total pressure of 1 atm. The partial pressure of water vapours is 0.3 atm. The contents of this vessel are transferred to another vessel havig one third of the capacity of original volume, completely at the same temperature, the total pressure of the system in the new vessel is :

A sample of air contains only N_(2), O_(2), and H_(2)O . It saturated with water vapours and total pressure is 6 "torr" . The vapour pressure of water is 40 "torr" and the mol ratio of N_(2):O_(2) is 3:1 . The partial pressure of N_(2) in the sample is

A sample of air contains only N_(2)O_(2) and H_(2)O . It is saturated with water vapours and total pressure is 640 torr. The vapour pressure of water is 40 torr and the molar ratio of N_(2):O_(2) is 3:1. The partial pressure of N_(2) in the sample is :
