    It is found that the molar mass calucated through colligative property doesn't match with the expected/ theoretical value of that element. This is called as abnormal colligative property. This is corrected by Vant Hoff Factor.

    To prepare 0.1 N HCl from concentrated HCl, you will need to dilute an amount of HCl to water.
    If we are to make, for example, a 1 L of 0.1 N HCl, the equation will be: (note: Normality of concentrated HCl is about 12 N)
    (12 N) x V1 = (0.1 N) x (1 L)
    solving for the volume V1 , we get:
    V1 = 8.33 x 10-3L = 8.33ml
    so to prepare a 1 L, 0.1 N HCl from a stock solution of concentrated HCl (12 N) .

    PH3 has lower boiling point than NH3 because the electronegativity of N is much higher than that of P. So, NH3 undergoes extensive H-bonding and hence, it exists as an associated molecule. To break these additional bonds, the large amount of energy is required while PH3 does not form H-bond and hence, exists as discrete molecule.
