At 300 K two gases are filled in two equal sized containers as given

What will be the pressure of A(g) (in mm of Hg) ?

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 ?

At 300 K a gaseous reaction A rarr B +C was found to follow first order kinetics . Starting with pure A the total pressure at the end of 20 minutes was 100 mm of Hg . The total pressure after the completion of the reactionn is 180 mm of Hg . The partial pressure of A ( in mm of Hg ) is :

O_(2) gas is placed in a 4 litre container containing 3 L of liquid water as shown and total pressure exerted by gases is 720mm Hg. What will be the pressure of O_(2)(g) if given container is attached to a empty container of 3 litre at same temperature? Given : [V.P. of H_(2)O at 27^(@)C=20mm of Hg]

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)?
