Final answer:
The density of the crown can be found using the density formula, which is mass divided by volume. If the crown is made of pure gold, its density should be 19.3 g/cm³.
Step-by-step explanation:
The density of the crown can be found by using the density formula, which states that density (d) is equal to mass (m) divided by volume (v). Since the crown is made of pure gold, we know its density is 19.3 g/cm³. We can find the volume of the crown by rearranging the density formula to solve for volume: v = m/d. If the crown is indeed made of pure gold and nothing else, it should have the same density as pure gold, which is 19.3 g/cm³.
