An unknown liquid has a freezing point of 25.5oC, however, it absorbs H2O (as impurity) on exposure to humid air. If the freezing point of a 125g sample of the liquid is 24.59 oC, how many grams of H2O are present in the sample? Kf values of the liquid and water are 4.68 oC/m and 1.86 oC/m respectively.
