Answer:

The answer is

7.80 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 = 156 g

1 mL = 1 cm³

20 mL = 20 cm³

volume = 20 cn³

The density of the metal is

[tex]density = \frac{156}{20} = \frac{39}{5} \\ [/tex]

We have the final answer as

7.80 g/cm³ to 3 significant figures

Hope this helps you
