Explanation:

(a).

volume = final volume of water - initial volume of water

Volume of metal cylinder = 88 - 80

We have the answer as

8.0 mL

(b).

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 8 mL

density = 3.21 g/mL

So we have

mass = 3.21 × 8

We have the answer as

25.68 g

Hope this helps you
