Question

Vapour pressure of pure water at 298 K is 23.8 mm Hg. 50 g of urea
(NH,CONH,) is dissolved in 850 g of water. Calculate the vapour pressure
of water for this solution and its relative lowering.​

Answer 1

Answer:

Explanation:

50 g of urea (NH2CONH2) is dissolved in 850 g of water. Hence, the vapour pressure of water in the given solution is 23.4 mm of Hg and its relative lowering is 0.0173.
