A teacher performing a demonstration finds that a piece of cork displaces 23.5 cm3 of water. The piece of cork has a mass of 5.7 g. What is the density of the cork

Density = 0.243 g/cm³

Explanation:

Volume of cork = 23.5 cm³

Mass = 5.7 g

To find the density of the cork;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

Substituting into the formula, we have;

Density = 5.7/23.5

Density = 0.243 g/cm³

d) physical means can be used to separate the components of air.
