Sasha did an experiment to study the solubility of two substances. She poured 100 mL of water at 20 °C into each of two beakers labeled A and B. She put 50 g of Substance A in the beaker labeled A and 50 g of Substance B in the beaker labeled B. The solution in both beakers was stirred for 1 minute. The amount of substance left undissolved in the beakers was weighed. The experiment was repeated for different temperatures of water and the observations were recorded as shown. Experimental Observations Substance Mass of Undissolved Substance at Different Temperatures (gram) 20 °C 40 °C 60 °C 80 °C A 12 11 9 8 B 45 40 34 31 Part 1: Which substance has a higher solubility? Part 2: Explain your answer for Part 1.

Answer:
Answer 1- The solubility of B is greater than that of A.
Explanation:
Answer 2-
The amount of substance dissolved in a given amount of solvent is defined as solubility. The solute's solubility increases as the solute dissolves, and decreases as the solute dissolves.
For the following observations:
At all temperatures, the mass of undissolved substance A is greater than the mass of substance B. This means that less solute is dissolved in the given amount of solvent.
As a result, substance B is more soluble than substance A.
