The one that has a higher concentration of solute and a lower concentration of water. Think about it. If you separated a 0.1 M solution of sucrose and a 0.75 M solution of sucrose with a selectively permeable membrane, which direction would the water move? Of course it would move from the 0.1 M solution into the 0.75 M solution. In the process, it would be doing work.
