Question

PLEASE ANSWER NO ONE IS ANSWERING AND I NEED

Part 1: Which substance has a higher solubility? Part 2: Explain your answer for Part 1.


Julia 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 40 37 34 30

B 15 14 13 12

Answer 1

the answer is b 15 14 13  and 12

Answer 2

the way to get this answer would be to find the answer that has less undissolved mass because you have to find the one with higher solubility, which also means the one that can dissolve the most mass.
