Answer:

The final volume in the cylinder will be #"41.0 mL"#.

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 cancel"g")/(7.00cancel"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"#
