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

PLEASE ANSWER NO ONE IS ANSWERING AND I NEED HELP ILL GIVE YOU ALL MY POINTS

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.

Solubility is the solute's ability to get dissolved in the solvent to form the saturated solution. The solubility of substance B in beaker B is more as compared to substance A.

What is solubility?

The capacity of the solute to form a solution with a solvent is defined by solubility. The solubility depends on many factors like pressure, mass, reactivity, temperature, etc.

The solubility is directly proportional to the temperature and increases with a rise in temperature. The mass of substance A is higher than that of substance B at all the temperatures and hence its size may be large.

Therefore, the mass of substance B is dissolved more at all temperatures as compared to substance A.
