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

Osmotic pressure = i CSTwhere C = Molarity of the solution         i = number of particles after dissociation (or) associationOsmotic pressure  ∞ Molarity(1) 10 gms of  C6H12O6 :  i = 1                                             (2) 10 gms of NH2CONH2: i = 1                                              (3) 10 gms of  C12H22O11: i = 1                                                    M2 > M1 > M3P2 > P1 >P3
