The density of sample X is 4 g/ml.
The given parameters;
The volume of the sample X is the increase in the volume of water after it was placed in the cylinder.
The density is obtained by dividing the mass of sample X by its volume as shown below;
[tex]Density = \frac{mass}{volume} = \frac{20}{5} = 4 \ g/ml[/tex]
Thus, the density of sample X is 4 g/ml.
