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
