Answer:

The answer is

0.0056 g/mL

Explanation:

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

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

From the question

volume = 3.4 mL

1 mg = 0.001 g

18.99 mg = 0.01899 g

So we have

[tex]density = \frac{0.01899}{3.4} \\ = 0.005585294..[/tex]

We have the final answer as

0.0056 g/mL

Hope this helps you
