Question 4 Leave the rocks submerged in the jars for about 90 minutes. Then use a
spoon to carefully scoop the rocks from the jar labeled 0% Acid. Dry the
rocks by patting, or blotting, them with a soft rag. After the rocks are
dry, measure their mass and record it on the sticky note. Use this
format: "Final Mass: ." Place the jar with the liquid on the counter and
place the dried rocks next to the jar. Repeat this process for the other
three jars. After you have recorded the final mass for each jar, complete
this table.
