WebAnswers. Problem 1. At 40 °C the solubility is 68 g per 100 g of water. So scaling, 68 x (20 / 100) = 13.6 g of potassium nitrate will dissolve in 20 g of water. Problem 2. Solubility of lead (II) nitrate at 90 o C is 118 g / 100 g water, and 64 g / 100 g water at 20 °C. Therefore for mass of crystals formed = 118 – 64 = 54 g (for 100 cm 3 ...
