If the four samples all had the same volume, which sample would have the greatest density? sample mass
W 47
X 223
Y 85
Z 312

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.
