Answer to Question #133556 in General Chemistry for Areej

Question

At a bazaar, someone is trying to sell you a small gold elephant. However, the elephant is not very heavy. It has a volume of approximately 25mL and a mass of 195g. Calculate the density of the elephant. Do you think the elephant is made of gold?
195

Answer 1

The density equals 195g / 25mL = 7.8 g/mL. The density of gold is approximately 19.3 g/mL. Therefore, this elephant is not made of gold. The one made of gold would be much heavier having the same volume.
