Consider the sugar–water phase diagram of Figure 9.1.

(a) How much sugar will dissolve in 1000 g of water at 80°C (176°F)?

---

(b) If the saturated liquid solution in part (a) is cooled to 20°C (68°F), some of the sugar precipitates as a solid. What will be the composition of the saturated liquid solution (in wt% sugar) at 20°C?

---

(c) How much of the solid sugar will come out of solution upon cooling to 20°C?
