Use the diagram to answer each question. About how many grams of potassium nitrate (KNO3) will settle out when a saturated solution made in 100 grams of water is cooled from 70°C to 50°C?

Astudent states that 9.0 g of baking soda will form an unsaturated solution in 100 g of water. what do you need to know to decide whether this statement is correct? a. the temperature of the water and the molar mass of baking soda b. the percent by volume of the solution and the solubility of baking soda c. the temperature of the water and the solubility of baking soda at that temperature
