Vapour pressure of pure water at `298 K ` is `23.8 mm Hg`. `50g` of urea `(NH_(2)CONH_(2))` is

30 g of urea (M=60g mol^(-1) ) is dissolved in 846g of water. Calculate the vapour pressure of water for this solution if vapour pressure of pure water at 298 K is 23.8 mm Hg. (b) Write two differences between ideal solutions and non-ideal solutions,

A solution of a non-volatile solute in water freezes at -0.30^(@)C . The vapour pressure of pure water at 298 K is 23.51 mm Hg and K_(f) for water is 1.86 degree//molal . Calculate the vapour pressure of this solution at 298 K .

A solution of non-volite solute in water freezes at -0.80^(@)C .The vapour pressure of pure water at 298 K is 23.51 mm Hg .and K_(f) for water is 1.86 degree per molal. Calculate the vapour pressure of this solution at 298 K .

The vapour pressure of water at 20^(@)C is 17 mm Hg Calculate the vapour pressure of a solution containing 2.8 g of urea (NH_(2)CONH_(2)) in 50 g of water .

The vapour pressure of pure water at 20^(@)C is 17.5 mm of Hg. A solution of sucrose is prepared by dissoving 68.4 g of sucrese in 1000 g of water. Calculate the vapour pressure of the solution.
