400 mL of `N_(2)` gas at 700 mm and 300 mL of `H_(2)` gas at 800 mm are introduced into a vessel of 2 L at the same temperature. Calculate the final pressure of the gas mixture.

500 ml oxygen at a pressure of 700 mm, 300 ml hydrogen at a pressure of 750 mm and 700 ml of nitrogen at a pressure of 600 mm are enclosed in a vessel of 1 litre capacity at 25^@C . Calculated the total pressure of the gas mixture.

400cc of N_2 at 600mm and 500cc of O_2 at 300mm are quantitatively transferred in to an empty vessel of X 2 L capacity. Calculate the pressure of the mixture and partial pressures.

400mL of CO_(2) gas at 0.892 bar pressure and 800mL of CH_(4) gas at 0.921 bar pressure are put into a 2L flask. Calculate the total pressure of the mixture assuming temperature is kept constant.

400mL of CO_(2) gas at 0.892 bar pressure and 800mL of CH_(4) gas at 0.921 bar pressure are put into a 2L flask. Calculate the total pressure of the mixture assuming temperature is kept constant.

The pressure of a gas in a vessel is 80 cm of Hg. Now 25% of the same gas is also introduced into the same vessel. If the process is done at the same temperature, find the final pressure of the gas.

At NTP the volume of a gas is 40 mL . If pressure is increased to 800 mm of Hg at the same temperature what will be the volume of the gas ?
