Question

A teacher performing a demonstration finds that a piece of cork displaces 23.5ml of water. The piece of cork has a mass of 5.7g. What is the density of the rock

Answer 1

Answer: 0.24g/ml
Given that:
Volume of water displaced = 23.5 ml
Mass of cork = 5.7 g
Density of the cork = ?
Recall that density is obtained by dividing the mass of a substance by the volume of water displaced.
i.e Density = Mass/volume
Density = 5.7g /23.5ml
Density = 0.24g/ml
∴Thus, the density of the piece of cork is 0.24g/ml
