Side A is half-filled with a solution of 2 M sucrose and 1 M glucose. Side B is half-filled with 1 M sucrose and 2 M glucose. Initially, the liquid levels on both sides are equal.

When the system illustrated above reaches equilibrium, the sugar concentrations on both sides of the U-tube will be ________.

• A) 2 M sucrose, 1 M glucose
• B) 1 M sucrose, 2 M glucose
• C) 1 M sucrose, 1 M glucose
• D) 1.5 M sucrose, 1.5 M glucose
