8.96cm3g
Explanation : To find density, we can use the formula as given below;
density ρ = \frac{mass(m)}{volume(v)}volume(v)mass(m)
Here, we have the mass as 89.6 g and the volume is 10.0 cm^{3}10.0cm3 ,
on calculating we get,
This means that the density of the copper sample is 8.96 g/ cm^{3}8.96g/cm3
