What is the relation between osmotic pressure of 5% aqueous solution of glucose (P₁) to that of 5% aqueous solution of urea (P₂)?

P₁ < P₂

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
