For a pressure at 1.2 atm, calculate the pressure head of water.

If the concentration of water vapour in the air is 1% and the total atmospheric pressure equals to 1 atm then the partial pressure of water vapours is

If the concentration of water vapour in the air is 1% and the total atmospheric pressure equals 1 atm then the partial pressure of water vapour is :

A mixture of H_(2) and N_(2) weighing 0.116 g is collected over water at 50^(@)C and occupies a volume of 275 mL when the total pressure is 1.0 atm. Calculate the precentage of H_(2) and N_(2) present. Calculated the vapour pressure of water at 50^(@)C is 92.5 torr.

The degree of dissociation of PCl_(5) at 1 atm pressure is 0.2 . Calculate the pressure at which PCl_(5) is dissociated to 50% ?

The degree of dissociation of PCl_(5) at 1 atm pressure is 0.2 . Calculate the pressure at which PCl_(5) is dissociated to 50% ?

Two litre of N_2 at 0^@C and 5 atm pressure are expanded isothermally against a constant external pressure of 1 atm until the pressure of gas reaches 1 atm. Assuming gas to be ideai, calculate work of expansion.

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)

A 3 litre flask contains 2.2 gms of CO_2 and some mass of oxgyen. If the pressure of the mixture is 1.2 atm at 27^@C , Calculate the partial pressure and the mass of oxygen.
