Daniel has a sample of pure copper. its mass is 89.6 grams (g), and its volume is 10 cubic centimeters (cm3). what’s the density of the sample?

0.11 g/cm3

8.96 g/cm3

11.1 g/cm3

896 g/cm3

Explanation:

the parameters given

mass of pure copper, m = 89.6g

volume of copper, v =

we are to find density, ρ = mass/volume

        89.6 g/

ρ = 8.96 g/
