Question

A teacher performing a demonstration finds that a piece of cork dicplaces 23.5mL of water. The piece of cork has a mass of 5.7g.what is the density of the cork?

Answer 1

The density of the piece of cork is calculated by dividing the mass of the cork (5.7g) by the volume of water displaced (23.5cm³), resulting in a density of approximately 0.2426 g/cm³.

Step-by-step explanation:

The student is asking to calculate the density of a piece of cork. The density of an object is calculated by dividing its mass by its volume. In this case, the density (d) can be calculated using the formula:

Density = Mass/Volume

The mass of the cork is given as 5.7g, and the volume of water displaced by the cork is 23.5mL (which is equivalent to 23.5cm³ since 1mL = 1cm³). Thus, the density of the cork is:

Density of cork = mass / volume

= 5.7g / 23.5cm³

≈ 0.2426 g/cm³

Therefore, the density of the cork is approximately 0.2426 g/cm³.
