Answer:

The answer is 7.94 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 = 324 g

volume = 40.8 cm³

We have

[tex]density = \frac{324}{40.8} \\ = 7.941176...[/tex]

We have the final answer as

7.94 g/cm³

Hope this helps you
