QUESTION #55 Osmotic Pressure
A solution is prepared by dissolving 0.3 text g of a non-volatile non-electrolyte solute 'A' of molar mass 60 text g mol^-1 and 0.9 text g of a non-volatile non-electrolyte solute 'B' of molar mass 180 text g mol^-1 in 100 text mL mathrmH_2mathrmO at 27^circtextC. Osmotic pressure of the solution will be [Given: R = 0.082 text L atm K^-1 text mol^-1]

QUESTION #62 Colligative Properties
'W' g of a non-volatile electrolyte solid solute of molar mass 'M' g text mol^-1 when dissolved in 100 text mL water, decreases vapour pressure of water from 640 text mm Hg to 600 text mm Hg. If aqueous solution of the electrolyte boils at 375 text K and K_b for water is 0.52 text K kg mol^-1, then the mole fraction of the electrolyte solute (X_2) in the solution can be expressed as (Given : density of water = 1 text g/mL and boiling point of water = 373 text K)
