At \(298K\), the vapour pressure of pure water is \(25\ torr\). The vapour pressure of water, when \(12\ g\) of urea \((\text{molar mass }=60\ g\ mol^{-1})\) and \(36\ g\) of glucose \((\text{molar mass }=180\ g\ mol^{-1})\) is dissolved in \(100\ g\) of water at the same temperature \((in\ torr)\) is
