Explanation:

<h2>(a).</h2>

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

density =  \frac{mass}{volume}  \\

From the question

mass of metal = 14 g

volume = 2.98 mL = 2.98 cm³

It's density is

density =  \frac{14}{2.98}  \\  = 4.69798657...

We have the answer as

4.70 g/cm³

<h2>(b).</h2>

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

Hope this helps you
