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?

2g of a non-electrolyte solute dissolved in 100g of benzene lowered the freezing point of benzene by 0.40 K. find the molar mass of the solute.

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

A plot is obtained for two volatile liquids A & B as follows. From the plot answer the following. What is the total pressure of the solution phase?

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.

At 300 K, 36 g of glucose present in a litre of its solution has an osmotic pressure of 4.98 bar. If the osmotic pressure of the solution is 1.52 bars at the same temperature, what would be its concentration?

A solution is prepared by dissolving 1.25g of oil wintergreen (methyl salicylate) in 99.0g of benzene has or boiling point of 80.31^@C . Determine the molar mass of this compound. (bp of pure benzene, 80.10^@C and K_b for benzene, 2.53^@Ckg mol -1 )

Explain when a non volatile solute is added to a liquid solvent, the vapur pressure of the solution decreases.

Define the term 'osmosis' and 'osmotic pressure'. What is the advantage of using osmotic pressure as compared to other colligative properties for the determination of molar masses of solute in solution.
