(a) The specific rotation of sucrose (table sugar) in water is 166.1 degrees mL g^–1 dm^–1. What is the observed optical rotation in a 1 dm path of a sucrose solution prepared from 5 g of sucrose and enough water to form 100 mL of solution?

(b) Chemist Ree N. Ventdawil has said to you that he plans to synthesize the enantiomer of sucrose so that he can measure its specific rotation. You politely inform him that you already know the result. Explain how you can make this claim.
