Question

In front of the room are 6 flasks of different sucrose solutions. the flasks contain solution that are either 0.0 m, 0.2 m, 0.4 m, 0.6 m, 0.8 m, or 1.0 m sucrose. unfortunately my colleague for got to label the flasks. devise a method for quantitatively determining which flask holds which solution.

Answer 1

Each flask is labeled and a sample is taken from each flask and labeled the same way. The water from each sample is boiled off and the mass of what remains is measured. The higher the molarity of the sample, the more sucrose that will be left behind.
