The solutions in the arms of the Utube are separated at the

The solutions in the arms of the U-tube are separated at the bottom by a selectively permeable membrane. The membrane is permeable to NaCl but NOT to glucose.

After diffusion and equilibrium:

       How many mols of sucrose are on side A? _______ side B? _________

       How many mols of glucose are on side A? _______ side B? _________

0.4 mols glucose 0.5 mols Naci Side Side A Initial setup B 0.8 mols glucose 0.4 mols Naci Membrane

Solution

sucrose is not given in the picture.

NaCl will be equal both the side it means

A: 0.45 mols

B: 0.45 mols (because of simple diffusion down to the concentration gradient)

since membrane is not permeable for glucose then the water from low concentration of glucose will move to the high glucose concentration and achieve the equilibrium after the glucose concentration will reach to the equal at both the sides

A: 0.6 mols

B: 0.6 mols
