If the gold in the crown was mixed with a less-valuable metal like bronze or copper, how would that affect its density?

Density can be defined as the compactness of any substance. It is the mass/volume of a substance.

Thus, if the gold crown is mixed with cheaper substances, such as bronze and copper, the density of the crown will decrease and it will become lighter.
