QUESTION #55 Osmotic Pressure
A solution is prepared by dissolving 0.3 g of a non-volatile non-electrolyte solute 'A' of molar mass 60 g mol⁻¹ and 0.9 g of a non-volatile non-electrolyte solute 'B' of molar mass 180 g mol⁻¹ in 100 mL H₂O at 27°C. Osmotic pressure of the solution will be [Given: R = 0.082 L atm K⁻¹ mol⁻¹]

QUESTION #62 Colligative Properties
'W' g of a non-volatile electrolyte solid solute of molar mass 'M' g mol⁻¹ when dissolved in 100 mL water, decreases vapour pressure of water from 640 mm Hg to 600 mm Hg. If aqueous solution of the electrolyte boils at 375 K and Kb for water is 0.52 K kg mol⁻¹, then the mole fraction of the electrolyte solute (X₂) in the solution can be expressed as (Given : density of water = 1 g/mL and boiling point of water = 373 K)
