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 P1 < P2 P1 > P2 P1 = \(\frac{P_2}{2}\)

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
