Question

Placing a sample of iron (II) oxide into a graduated cylinder makes the water volume increase 12.0 ml. The weight of the sample is 76.6g. What is it’s density? (Round to the nearest hundredths)

Answer 1

it 76.6

Step-by-step explanation:

cause it is what it is

Answer 2

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
