Q. $100\, g$ of liquid A (molar mass $140\, g\, mol ^{-1}$ ) was dissolved in $1000\, g$ of liquid B (molar mass $180\, g\, mol ^{-1}$ ). The vapour pressure of pure liquid $B$ was found to be $500$ torr. Calculate vapour pressure of $A$ (in torr) the solution if the total vapour pressure of the solution is $475$ torr.
