refer to the graph above. in order to have a saturated solution, how many grams of potassium nitrate, kno₃, need to be dissolved in 100 grams of water at 20°c.
Answer
Answer:
30
Explanation:
Step1: Locate 20°C on x - axis
Find 20°C on the temperature axis.
Step2: Locate KNO₃ curve
Identify the curve for potassium nitrate ($KNO_3$).
Step3: Read solubility value
Read the solubility value on the y - axis where the 20°C line intersects the $KNO_3$ curve, which is 30 g of salt per 100 g of water.
