The densities of the coinage metals (copper, silver and gold) are as follows:
Copper = 8.95 g/mL
Silver = 12.59 g/mL
Gold = 19.32 g/mL
A sample of material is found to have a mass if 33.03 grams, and have a volume of 2.624 mL. This is a sample of which of the coinage metals?

Question

Quizplus · Accepted Answer

The density of the sample is calculated by dividing its mass by its volume: 33.03 grams / 2.624 mL = 12.59 g/mL, which matches the density of silver.
