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

Answer: 0.24g/ml

Explanation:

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
