Answer:
The answer is
3.83 g/mL
Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 76.6 g
volume = 12 mL
The density of iron (ll) oxide is
[tex]density = \frac{76.6}{12} \\ = 6.38333333...[/tex]
We have the final answer as
6.38 g/mL
