Answer:

The answer is 6.83 g/mL

Step-by-step explanation:

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


density = (mass)/(volume) \\

From the question

mass of iron (II) oxide = 76.6 g

volume = 12 mL

We have


density = (76.6)/(12) \\ = 6.3833333...

We have the final answer as

6.83 g/mL to the nearest hundredth

Hope this helps you
