Answer:

The density of sample X is 4 g/ml.

The given parameters;

- <em>Mass of sample X = 20 g</em>
- <em>Initial volume of water before the sample was placed = 14 ml</em>
- <em>Final volume of water after the sample was placed = 19 ml</em>

The volume of the sample X is the increase in the volume of water after it was placed in the cylinder.

- Volume of sample X = 19 ml - 14 ml = 5 ml
- Mass of sample of X = 20 g

The density is obtained by dividing the mass of sample X by its volume as shown below;

Thus, the density of sample X is 4 g/ml.
