Given the following, how do you calculate (a) the mass of water required to dissolve one hundred grams of sugar at 100°C and (b) the amount of sugar that remains in solution when the mixture in (a) is cooled to 20 C?
The solubility of sugar (sucrose) is 487 g/100 g water at 100°C and 204 g/100 g water at 20°C
The solubility of sugar (sucrose) is 487 g/100 g water at 100°C and 204 g/100 g water at 20°C

(a) 20.5 g of water required; (b) 41.9 g of sugar remain in solution.
Explanation:
(a)
You know that 100 g water dissolve 487 g sugar.
∴ 100 g of sugar dissolve in
So, 20.5 g of water contain 100 g of sugar at 100 °C.
(b)
At 20 °C, 20.5 g of water contain
