Vedmedyk [2.9K]

Explanation:

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

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