A solid mixture consists of 25.5 g of KNO3 (potassium nitrate) and 4.5 g of K₂SO4 (potassium sulfate). The mixture is added to 130. g of water. Use this solubility curve (Figure 1) to answer the questions. Part B If the solution described in the introduction is cooled to 0 °C, what mass of KNO3 should crystallize? Enter your answer numerically in grams. View Available Hint(s) 15| ΑΣΦ ?
