Explanation:

(a).

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

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

From the question

mass of metal = 14 g

volume = 2.98 mL = 2.98 cm³

It's density is

[tex]density = \frac{14}{2.98} \\ = 4.69798657...[/tex]

We have the answer as

4.70 g/cm³

(b).

The metal is not copper since it's density is less than that of copper.

Hope this helps you
