Question

A solution containing one mole of glucose (C6H12O6) and a separate solution containing one mole of sucrose (C12H22O11), are each dissolved in one kilogram of water. Both solutions exhibit the same colligative properties. How is this possible?

Answer 1

colligative properties are based on two things: the van't Hoff factor, and the molality. In this case, both have a van't Hoff factor of 1, and equal molality (1 m).
