FREE Expert Solution

For the first part, we're being asked to determine how many grams of KCl remain in the solution at 20°C.

We're given a solution containing 84.9 g KCl in 210 g H2O at 50 °C then cooled to 20°C

solubility of KCl at 20°C:    34.0 g KCl/100 g H2O

We're going to use ratio and proportion to calculate how much KCl is left:
