The value of `K_(f)`for water is `1.86^(@)`, calculated from glucose solution, The value of `K_(f)`for water calculated for NaCl solution will be,

If K_(f) for water is 1.86^(@)C"mol"^(-1) , a 0.1 m solution of urea in water will have the freezing point of

If K_(f) value of H_(2) O is 1.86. The value of Delta T_(f) for 0.1 m solution of non-volatile solute is

A 0.1 molal aqueous solution of a weak acid is 30% ionized. If K_(f) for water is 1.86^(@)C//m , the freezing point of the solution will be.

The freezing point of a solution containing 5.85 g of NaCl in 100 8 of water is -3.348^(@)C . Calculate van't Hoff factor for this solution. What will be the experimental molecular weight of NaCl? ( K_(f) for water = 1.86 K kg mol^(-1) , at. wt. Na = 23, Cl = 35.5)
