SUMMARY
The discussion focuses on calculating density using the formula Density = Mass/Volume, with specific examples provided. For the first example, a mass of 79.4 grams and a volume of 29.8 cubic centimeters yield a density of 2.6 g/cm³. In the second example, a mass of 25.4 grams and the same volume results in a density of 0.85 g/cm³. The correct notation for density units is emphasized as grams per cubic centimeter (g/cm³), highlighting its importance in identifying materials.
