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
