In the metric system the unit of density for a liquid or solid is measured in g/mL or g/cm3 . The cm3 volume unit used with solids is numerically equal to mL volume unit used with liquids. That is, 1 mL = 1 cm3
In this experiment you will determine the density of several liquids and compare the physical properties of those liquids.
Which is heavier, a pound of aluminum or a pound of lead? The answer, of course, is neither, but many people confuse the words “heavy” and “dense” “Heavy” refers to mass only. Density is the mass of a substance contained in a unit of volume. Lead is a very dense metal and contains a large quantity of matter in a small
volume, while aluminum, being much less dense, contains a smaller quantity of matter in the same volume.
