question 45

Multiple Choice

Figure 5.3
The solutions in the arms of a U-tube (Figure 5.3) are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0.5 M sodium chloride (NaCl) , and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Initially, the volume in both arms is the same. Refer to the figure to answer the following questions.
-If you examine side A in the figure after three days, the concentrations of glucose and NaCl should be

• A) 0.4 M glucose, 0.45 M NaCl.
• B) 0.6 M glucose, 0.5 M NaCl.
• C) 0.6 M glucose, 0.45 M NaCl.
• D) 0.8 M glucose, 0.4 M NaCl.
• E) 0.8 M glucose, 0.5 M NaCl.
