Question

The osmotic pressures of equimolar solutions, at the same temperature, of (A) glucose, (B) K,SO and (C) KNO, will be in the order 4 a) A>B>C b) C>B>A c) B> C>A d) C>A>B​

Answer 1

Answer:

k2so4 has 3 ions kno3 has 2 ions glucose has one...so more the ions more the op...B>C>A

Answer 2

Answer:

Osmotic pressure is a colligative property, and more the number of particles more the osmotic pressure.

π=iCRT

Hence, BaCl2>NaCl>Glucose since the concentration is same and i for BaCl2 is 3, NaCl is 2 and glucose is 1.
