Question

A necklace found at a pawn shop is 192 grams and has a volume of 19.5 cubic centimetres. What metal is the necklace made of?

Answer 1

Bronze

Explanation:

Let's calculate the density of this necklace.

Density is mass divided by volume: m / v. Here, we know the mass is m = 192 grams, and we also know the volume is v = 19.5 cubic centimetres. Plug these into the equation:

d = m / v

d = 192 / 19.5 = 9.85 g / cm³

Looking at the chart, the closest density to this is that of bronze, which is 9.87. So, the necklace is likely made of bronze.
