The Total solution for NCERT class 6-12
Vapour pressure of pure water at298 K is 23.8 mm Hg. 50 g of urea (NH2CONH2) is dissolvedin 850 g of water. Calculate the vapour pressure of water for this solution andits relative lowering.
Hence, the vapour pressure ofwater in the given solution is 23.4 mm of Hg and its relative lowering is0.0173.
