Answer:

The answer is 8.89 g/cm³

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 75.6 g

volume of copper = 8.5 cm³

We have

[tex]density = \frac{75.6}{8.50} \\ = 8.894117647...[/tex]

We have the final answer as

8.89 g/cm³

Hope this helps you
