A solution containing 30g of non-volatile solute exactly in 90g of water has a vapour pressure of 2.8 kPa at 298 K. Further, 18 g of water is then added to the solution and the new vapour pressure becomes 2.9 kPa at 298 K. Calculate: molar mass of the solute

A solution containing 30 g of non-volatile solute exactly in 90g of water has a vapour presure of 2.8K Pa at 298K. Further 10g of water is added to this solution. The new vapour pressure becomes 2.9K Pa at 298K. Calculate 298K. The molar mass of the solute

A solution containing 30 g of non-volatile solute exactly in 90g of water has a vapour presure of 2.8K Pa at 298K. Further 10g of water is added to this solution. The new vapour pressure becomes 2.9K Pa at 298K. Calculate Vapour presure of water at 298K

An aqueous solution of 2 percent non-volatile solute exerts a pressure of 1.004 bar at the normal boiling point of the solvent. What is the molecular mass of the solute?

Explain why Vapour pressure of a liquid decreases when a non-volatile solute is added to it.

The vapour pressure of water is 12.3 kPa at 300 K. Calculate vapour pressure of 1 molal solution of a non-volatile solute in it.

2000 cm^3 of an aqueous solution of a protein contains 1.26 g of the protein. The osmotic pressure of such a solution at 300K is found to be 2.57 … 10^(-3) bar. Calculate the molar mass of the protein.

Vapour pressure of pure water at 298K is 23.8 mm Hg. 50g of urea (NH_2CONH_2) is dissolved in 850 g of water. Calculate the vapour pressure of water for this solution and its relative lowering.

100 g of liquid A (molar mass 140 g mol^-1) was dissolved in 1000g of liquid B (molar mass 180 g mol^-1) . The vapour pressure of pure liquid B was found to be 500 torr: Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution if the total vapour pressure of the solution is 475 Torr.
