Density is a value for mass, such as kg, divided by a value for volume, such as m^3. Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. 

Mass of gold = 5 cm³ (19.3 g/cm³) = 96.5 g

Therefore, the correct answer is option D.
