The molecules............can transfer from..............

• (X) & (Z)/from solution 1 to solution 2

• (Y)/from solution 1 to solution 2

• (X) & (Z)/from solution 2 to solution 1

The diagram shows a visking tubing experiment involving sugar solutions of different concentrations.Solution R = 1% sucrose solution

Solution S = 3% sucrose solutionThe experiments was left for 30 minutes.Predict the result of the experiment.

• A. Water moves into the bag and the contents of the bag gain mass

• B. Water moves out of the bag and the contents of the bag lose mass

• C. Water moves out of the bag and the contents of the bag gain mass

• D. Water moves into the bag and the contents of the bag lose mass
