Introduction
Density is the ratio of mass to volume; d = m/V. Because d is such a ratio, it is an intensive
property. That is, d is a property of the material, but does not depend on how much you have.
[d also depends on conditions, especially temperature and pressure. Effects of
these variables are very large for gases, but modest for solids and liquids. We
will ignore them here.]
The Greek letter
ρ
(rho) is also used for density.
The density equation contains three terms (d, m, V). In general, in density problems you know
two of these and want to calculate the third.
Most density problems can be solved by careful attention to the units, even if you do not
precisely remember the above equation. In fact, this worksheet assumes that you generally
understand the use of dimensional analysis as a problem solving tool; see the Dimensional
Analysis worksheet if you want some help with that topic.
