Answer: 8.96 g/cm3
Explanation: Density is defined as the mass of a substance contained in unit volume of a substance.
[tex]Density=\frac{mass}{volume}[/tex]
Given : mass of pure copper = 89.6 g
Volume of copper= [tex]cm^3[/tex]
thus [tex]Density=\frac{89.6g}{10cm^3}[/tex]
[tex]\text {Density of the sample of copper is}}=8.96g/cm^3[/tex]
