10 ml of ethane gas is mixed with 40ml oxygen gas in an eudiometer tube at `30^@C` and fired such that complete reaction occurs. When the resulting gases are cooled to `30^@C`, the volume of eudiometer becomes 26ml. What is the vapour pressure of water at `30^@C`? Neglect the volume occupied by liquid water. Pressure is 1 atm and constant throughout.

A gas has a volume 250 mL at 27^@C . The volume is doubled by heating the gas at constant pressure. What will be the new temperature ?

A sample of a gas occupies 600 mL at 27^(@)C and 1 atm. What will be the volume at 127^(@)C if the pressure is kept constant ?

450mL of oxygen gas at 20^(@)C" is heated to "50^(@)C. What is the new volume of the gas at constant pressure?

450mL of oxygen gas at 20^(@)C" is heated to "50^(@)C. What is the new volume of the gas at constant pressure?

A sample of neon gas has a volume of 248 mL at 30^(@)C and a certain pressure. What volume would it occupy if it were heated to 60^(@)C at the same pressure?

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)

9.0 mL of a mixture of CH_4 and C_2H_4 is mixed with 30.0 mL of O_2 and the mixture is exploded in an eudiometer tube. On cooling, the resulting gas mixture occupy a volume of 21.0 mL. on shaking the residual gas with KOH, the volume becomes 7.0 mL. Find the volumes of CH_4 and C_2H_4 in the mixture (All volumes are measured at the same temperature and pressure)

300 mL of oxygen gas at - 10^(@)C are heated to 10^(@)C . What is the new volume if pressure remains constant ?

If 250ml of N_(2) at 30^(@)C and a pressure of 250mm Hg are mixed with 400ml of CH_(4) at 30^(@)C and pressure of 300mm Hg so that the volume of the resulting mixture is 350ml, what will be the final pressure of the mixture at 30^(@)C ?

If 250ml of N_(2) at 30^(@)C and a pressure of 250mm Hg are mixed with 400ml of CH_(4) at 30^(@)C and pressure of 300mm Hg so that the volume of the resulting mixture is 350ml, what will be the final pressure of the mixture at 30^(@)C ?
