Question

The following solutions were prepared by dissolving 10 g of glucose (C₆H₁₂O₆) in 250 ml of water (P₁), 10 g of urea (CH₄N₂O) in 250 ml of water (P₂) and 10 g of sucrose (C₁₂H₂₂O₁₁) in 250 ml of water (P₃). The right option for the decreasing order of osmotic pressure of these solutions is :

(1) P₂ > P₁ > P₃

(2) P₁ > P₂ > P₃

(3) P₂ > P₃ > P₁

(4) P₃ > P₁ > P₂
