Question

Placing a sample of iron (ll) oxide into a graduated cylinder makes the water volume increase 12.0 mL. The weight of the sample is 76.6 g. What is its density?

Answer 1

he answer is

3.83 g/mL

Step-by-step explanation:

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

From the question

mass = 76.6 g

volume = 12 mL

The density of iron (ll) oxide is

Step-by-step explanation:

Answer 2

The answer is

3.83 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 = 76.6 g

volume = 12 mL

The density of iron (ll) oxide is

`density = (76.6)/(12) \\ = 6.38333333...`

We have the final answer as

6.38 g/mL

Hope this helps you
