WebAug 6, 2024 · Density Formula Examples Example 1. A piece of gold has a mass of 115.92 grams and a volume of 6 cm 3.What is its density? d = m/v . d = 115.92g/6cm 3. d = 19.32g/cm 3. Note that the density of a ... WebMar 21, 2024 · Density is a physical property that is defined as a substance’s mass divided by its volume: density = mass volume d = m V. Density is usually a measured property of a substance, so its numerical value affects the significant figures in a calculation. Notice that density is defined in terms of two dissimilar units, mass and volume.
