Answer:

Density, $d=6.38\ g/cm^3$

Explanation:

It is given that, placing a sample of iron (II) oxide into a graduated cylinder makes the water volume increase 12.0 mL.

It means that the volume of the sample is 12 mL

The weight of the sample is 76.6 g

We need to find the density of the sample.

12 mL = 12 cm³

The formula of density is given by :

$d=\dfrac{m}{V}\\\\d=\dfrac{76.6\ g}{12\ cm^3}\\\\d=6.38\ g/cm^3$

So, the density of the sample is $6.38\ g/cm^3$ .
