Question

Tanya was measuring the ability of different substances to dissolve in water. She mixed in each test tube the same amount of water and substance. She then measured the level of undissolved solute at the bottom of the test tube once it settled. Her results are in the chart. which best describes through solutions? A)Substance W has the greatest solubility. B)Substance X has the greatest solubility. C)Substance Y has the greatest solubility. D)Substance Z has the greatest solubility.

Answer 1

Answer: Option (D) is the correct answer.

Explanation:

It is known that 1 centimeter contains 10 millimeter. Therefore, unit millimeter (mm) is smaller than centimeter (cm).

So, when different substances were dissolved in water then according to the given chart, substance which shows smallest number in millimeters will have the greatest solubility.

Thus, we can conclude that substance Z has the greatest solubility.

Answer 2

Answer:

D)Substance Z has the greatest solubility.

Explanation:

As Tanya actually put the same amount of subtances in the same amount of water, the leftovers that settled at the bottom of each test tube were the amount of that given substance that couldn´t dissolve in the water, so the one that has the least amount of substance settled in the tube is the one with the greatest solubility, as substance Z had only 0.1 mm left, that is the one with the greatest solubility.
