Solutions · Osmotic pressure of mixed solutes

A solution is prepared by dissolving 0.3 g of a non-volatile non-electrolyte solute ‘A' of molar mass 60 g mol−1^{-1} and 0.9 g of a non-volatile non-electrolyte solute ‘B' of molar mass 180 g mol−1^{-1} in 100 mL HX2O\ce{H2O} at 27∘^\circC. Osmotic pressure of the solution will be

[Given : R=0.082R = 0.082 L atm K−1^{-1} mol−1^{-1}]

  1. (1)1.23 atm
  2. (2)2.46 atm
  3. (3)0.82 atm
  4. (4)1.47 atm
