Question

A 10% glucose solution is placed in a dialysis tubing bag. the dialysis tubing bag is placed in a beaker that contains a 5% glucose solution. where is the highest concentration of water found?

Answer 1

The highest concentration of water would be found in the 5% solution. The concentration given above is percent of glucose, so the solution contain 5% of glucose and 95% of water. Comparing it to 10% of glucose solution which will have 10% glucose and 90% water, clearly, it is the 5% solution that has the highest amount of water in the solution. Percentage by a certain unit is the amount of that unit of a component in a mixture per 100 units of the total mixture.
