At `298 K` , the vapour pressure of water is `23.75 mm Hg`. Calculate the vapour pressure at the same temperature over `5%` aqueous solution of urea. `[CO(NH_(2))_(2)]`.

The vapour pressure of water is 17.54mm Hg at 293 K. Calculate vapour pressure of 0.5 molal solution of a solute in it.

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 water at 20^@ is 17mm, Hg. Calculate the vapour pressure of a solution containing 2.8 g of urea (NH_2CONH_2) in 50 g of water.

At 25^(@) C , the saturated vapour pressure of water is 3.165 k Pa (23.75 mm Hg). Find the saturated vapour pressure of a 5% aqueous solution of urea (carbamide) at the same temperature. (Molar mass of urea = 60.05 g mol^(-1) )
