Background - Calculating Density The density of an object is defined as the ratio of the object's mass with respect to the object's volume. In this lab, density will be described using the units of gem . The equation for density is where is D is density in g/cm3, m is mass in g, and I is volume in cm. Ping pong ball ~ 0.0085 g/cm3 (normal) Wood = 0.70 g/cm3 Ice ~ 0.92 g/cm3 Water = 1.00 g/cm3 Salt water = 1.03 g/cm3 Ping pong ball = 1.23 g/cm3 (compressed) Maple Syrup = 1.33 g/cm3 Mild Steel = 7.85 g/cm3 (iron alloy with
