Answer:
If four samples have the same volume, the sample with the highest mass will have the highest density, i.e. sample Z.
Explanation:
The density expresses the amount of mass that occupies a given volume, and knowing the mass and volume of a solid, the density can be determined by the formula:
ρ = m/V
From this formula it can be determined that density is directly proportional to mass and inversely proportional to volume.
Of the four samples, the highest mass is in the sample Z (312), so this sample has the highest density.
