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.

A 2-column table with 4 rows. The first row titled substance has entries W, X, Y, and Z. The second column titled level of undissolved solute has entries 0.5 millimeters, 1.0 centimeters, 0.5 centimeters, 0.1 millimeters.
Which best describes the solutions?

Substance W has the greatest solubility.
Substance X has the greatest solubility.
Substance Y has the greatest solubility.
Substance Z has the greatest solubility.

Substance Z has the greatest solubility.

Explanation: with the same amount added, Z left the least undissolved (0.1 mm), so the most of it dissolved (compare: W 0.5 mm, Y 5 mm, X 10 mm).
