Answer:
Density, [tex]d=6.38\ g/cm^3[/tex]
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 :
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{76.6\ g}{12\ cm^3}\\\\d=6.38\ g/cm^3[/tex]
So, the density of the sample is [tex]6.38\ g/cm^3[/tex].
