  What is meant by Vant HofFs factor? The osmotic pressure of 0.0103 molar solution of an electrolyte is found to be 0.70 atm at 27°C. Calculate the Van't Hoff factor. [R = 0.082 Leter ] What conclusion do you draw about the molecular state of the solute in the solution?                                                                                                                                                             5

Answer:

  Vant Hoffs factor is the ratio of normal molecular mass to the observed molecular mass or the ratio of observed colligative property to normal colligative property. It is denoted by.                                                                    1                                                                                                                                                                Numerical:                                                                                                                                                                                        1                                                                                                                   1                                                                                                                                  1
