Two vessels whose volumes are in the ratio `2:1` contains nitrogen and oxygen at 800 mm and 680 mm pressure respectively, when they are connected together, what will be the pressure (in cm of Hg) of the resulting mixture ?

Two vessels of capactie 1.5 L and 2.0 L containing hydrogen at 750 mm pressure and oxygen at 100 mm pressure, respectivity are connected to each other through a valve. What will be the final pressure of the gaseous mixture assuming that the temperature remains constant?

Equal volume of two gases which do not react together are enclosed in separate vessels. Their pressures are 10mm and 400mm respectively. If the two vessels are joined together, then what will be the pressure of the resulting mixture (temperature remaining constant)?

The volumes of two vessels at same temperature are in the ratio of 2 : 3 . One vessel contains H_(2) and other N_(2) at 600 mm and 900 mm respectively. The final pressure when they are connected together is : (Assume that N_(2) and H_(2) react to form NH_(3) )
