Urea forms an ideal solution in water. Determine the vapour pressure of an aqueous solution contianing 10% by mass of urea at `40^@C`. (Vapour pressur of water at `40^@C`=55.3 mm of Hg)

Calculate the vapour pressure of an aqueous solution containing 5% by mass of urea (NH_2CON_2) at 298K. The vapour pressure of water at 298K is 23.75 mm Hg.

Why the vapour pressure of saline solutions is lower than that of pure water ?

The vapour pressure of an aqueous solution of glucose is 750 mm of mercury at 100^@ C . Mole fraction of solute will be

An aqueous solution of methanol has vapour pressure

Why the vapour pressure of a solution of glucose in water is lower than of pure water

If the vapor pressure of a dilute aqueous solution of glucose is 750 mm of Hg at 373 K , then molality of solute is

The degree of dissociation of Ca(NO_3)_2 in dilute aqueous solution containing 7.0 g of the salt per 100 g of water at 100^@C is 70 percent. If the vapour pressure of water at 100^@C is 760 mm, calculate the vapour pressure of the solution.

The lquid A and B from ideal solutions. At 300 K, the vapour pressure of solution containing 1 mole of A and 3 mole of B is 550 mm Hg. At the same tempreature, if one more mole of B is added to this solution, the vapour pressure of the solution increases by 10 mm Hg. determinethe vapour pressure of A and B in their pure states (in mm Hg):

Estimste the lowering of vapour pressure due to the solute (glucose) in a 1.0 m aqueous solution at 100^(@)C :
