Question

The relationship between osmotic pressure at 273 K when 10 g glucose (p1), 10 g urea (p2) and 10 g sucrose (p3) are dissolved in 250 mL of water, is (A) P1 > P2 > P3 (B) P3 > P1 > P2 (C) P2 > P1 > P3 (D) P2 > P3 > P1

Equal weight (10 g) of all electrolytes has been used. Higher the molecular weight, lower the number of moles and lower the magnitude of colligative properties. i.e.; osmotic pressure.
Molecular weight order : sucrose > glucose > urea.
Osmotic pressure order: urea > glucose > sucrose.

Q. The relationship between osmotic pressure at $273 K$ when $10 g$ glucose $(p_{1}), 10 g$ urea $(p_{2})$ and $10 g$ sucrose $(p_{3})$ are dissolved in $250 m L$ of water, is

$P_{1} > P_{2} > P_{3}$

$P_{3} > P_{1} > P_{2}$

$P_{2} > P_{1} > P_{3}$

$P_{2} > P_{3} > P_{1}$
