Solubility

1. Use the graph to answer the following questions. 1. What mass of solute will dissolve in 100mL of water at the following temperatures?a. KNO3 at 70°C = 130 gb. NaCl at 100°C= 40 gc. NH4Cl at 90°C= 70 gd. Which of the above three substances is most soluble in water at 15°C. KI 2. Label the following solutions as saturated or unsaturated. If unsaturated, write how much more solute can be dissolved in the solution. Solution Saturated or Unsaturated a solution that contains 70g of NaNO3 at 30°C (in 100 mL H2O) Unsaturated a solution that contains 50g of NH4Cl at 50°C (in 100 mL H2O) Saturated a solution that contains 20g of KClO3 at 50°C (in 100 mL H2O) Saturated a solution that contains 70g of KI at 0°C (in 100 mL H2O) Unsaturated 3.
