This chart gives the physical properties of copper. How does the density of a 4-g sample of copper compare to that of a 12-g sample

of copper?

• Its density is one-half the density of the 12-g sample.

• Its density is the same density as the 12-g sample.

• Its density is twice the density of the 12-g sample.

• Its density is three times the density of the 12-g sample.
