0.1 mol of sugar was dissolved in 1 kg of water. The freezing point of the solution was found to be 272.814 K. What conclusion would you draw about the molecular state of sugar? K_(f) for water is "1.86 K kg mol"^(-1).

Answer»


Solution :Proceed as in Solved Problem 1 or calculate the MOLECULAR MASS of sugar from the given the data which COMES out ot be 342, i.e., same as the NORMAL molecular mass of sugar.
