What will be the pressure of the gas mixture when 0.5 litre of `H_(2)`

1.	What will be the pressure of the gas mixture when 0.5 litre of `H_(2)` at 0.8 bar and 2.0 litre of oxygen at 0.7 bar are introduced in a 1 litre vessel at `27^(@)C` .
Answer» For `H_(2) n = (PV)/(RT) = (0.8 xx 0.5)/(RT) = (0.4)/(RT)` For `O_(2) n = (0.7 xx 2.0)/(RT) = (1.4)/(RT)` `:.` Total moles in mixture ` =(0.4)/(RT) + (1.4)/(RT) = (1.8)/(RT)` Using `PV = nRT` for 1 litre container Now `P_(mixture) xx 1 = (1.8)/(RT) xx RT = 1.8` bar

A container holds 3 liter of `N_(2(g))` and `H_(2)O_((l))` at `29^(@)C` The prssure is found to be 1 atm The water in container is instantaneously electrolysed to give `H_(2)` and `O_(2)` following the reaction `H_(2)O_(l) rarrH_(2(g)) +(1)/(2)O_(2_(g))` At the end of electrolysis the pressure was found to be `1.86atm` calculate the amount of water present in the container If the aqueous tension of water at `29^(@)C` is `0.04 atm ` .
