The density of sample X is 4 g/ml.

The given parameters;

  • Mass of sample X = 20 g
  • Initial volume of water before the sample was placed = 14 ml
  • Final  volume of water after the sample was placed = 19 ml

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;

[tex]Density = \frac{mass}{volume} = \frac{20}{5} = 4 \ g/ml[/tex]

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