What is the relation between osmotic pressure of 5% aqueous solution of glucose (P1) to that of 5% aqueous solution of urea (P2)?
Answer & explanation
Correct answer: option 2
Greater the molar concentration, greater is the osmotic pressure.
No of moles is directly proportional to the molar concentration at constant volume.
No of moles of glucose = \(\frac{5}{180}\)
No of moles of urea = \(\frac{5}{60}\)
Hence, P1 < P2
