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.

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
