Would the ratio of solute to solvent in a sucrose solution be the same as in a glucose solution?

Answer 1

No. For the physical formula ratio, of [solute:solvent] to be the same, you would have to use twice as much glucose as sucrose, to make the solution; because sucrose is a disaccharide. But, when preparing the solution, the actual weight used will be approximately the same. You have a solution, with solute sucrose, at 1C ratio. Weighing the same amount of glucose (in grams), will make a solution of 2C ratio. General expression is Glucose:Sucrose::2:1.

Answer 2

No, the ratio of solute to solvent would not necessarily be the same in a sucrose solution as in a glucose solution. Sucrose and glucose are different molecules with different molecular weights, so to achieve the same concentration in solution, you would need different amounts of each solute.
