Explanation:
Use the density formula to determine the volume of the piece of metal.
density
=
mass
volume
Rearrange the equation to isolate volume.
volume
=
mass
density
volume
=
147
g
7.00
g
mL
=
21.0 mL
The final volume in the cylinder after adding the piece of metal is
20.0 mL
+
21.0 mL
=
41.0 mL
