Mass, Volume, and Density Version 5 Eileen Pérez, Ph.D., Brian Butts, and Laura B. Sessions, Ph.D. In this experiment, which will take two lab periods, you will use common glassware and equipment in order to study the physical property of density. Objectives • Recognize and utilize common glassware and equipment.The density of an object is defined as the ratio of its mass to its volume: Density = Mass Volume (1.2.1) (1.2.1) Density = Mass Volume. For an example of density, consider the following: Imagine a brick that is made of Styrofoam. Imagine a second brick that is made of lead.
