Densities of binary mixtures of glucose, fructose and sucrose with formamide solvent were measured at 298.15K. From these data, the apparent molar volumes of carbohydrates at infinite dilution were obtained. The cavity volume and the interaction volume between solute and solvent were evaluated by two methods. One is a modified scaled particle theory, which takes into account of the real molecular shape. Another is a combination of a geometrically consideration with a group additive approach, which can be used to analyze molecules of arbitrary shape. The calculated results by these two methods were compared with the results in water.
