A solution of 20.0 g KClO₄ in 500.0 g of water is brought to a temperature of 40 °C.

(a) Refer to Figure 14-10 and determine whether the solution is unsaturated or supersaturated at 40 °C.

(b) Approximately what mass of KClO₄, in grams, must be added to saturate the solution (if originally unsaturated), or what mass of KClO₄ can be crystallized (if originally supersaturated)?
