Answer 2

Answer:

The volume of copper piece is equal to 5cm³.

The density of copper is equal to 8.8gcm⁻³.

Explanation:

Given: the mass of the copper piece, $m=44g$

Volume of water in the measuring cylinder $V=12ml$

The total volume after adding copper piece in water $V'=17ml$

We can find the volume of the copper piece by subtracting the volume of water from the total volume water and copper piece.

Volume of copper piece = (Volume of water & copper piece) - (volume of water)

So, Volume of copper piece $= V' - V$

                                              $= 17 -12 \\ =5ml \\= 5cm^{3}$

Density of copper = mass/ volume

                               $=\frac{44}{5} g/ml$

                               $=8.8gcm^{-3}$

Therefore, density of copper piece is equal to  8.8gcm⁻³.
