If the solid is soluble in water, you'll end up with a solution. For example, sugar is a solid, but it dissolves in water. So you couldn't tell the density of sugar (at least not in the direct way of the displacement method) by placing it in water..
This would also apply to salt, sand, ect.

If the solid is hollow on the inside, then the density formula (D = mass/volume) will calculate a density which is less than the density of the substance that the solid is made of. Another reason that it might not work: If the object has a density which is less than water (normally the liquid that is used to submerge and determine displacement) then the object will float at the top, with part of the object above the surface of the liquid. This portion which is out of the water does not get measured.

How do you work out the density of something?
Density is calculated by dividing the mass of an object by its volume. The formula for density is: Density = mass / volume. The units for density are typically grams per cubic centimeter (g/cm^3) for solids and liquids, and grams per milliliter (g/ml) for liquids.
How do you work out the volume using density and mass?
Since density is defined as mass divided by volume, it follows that if you divide mass by density you will get volume. For example: 10 grams divided by 2grams/cc = 5 cc. (cc is cubic centimeter)
How do you find the diameter of an asteroid knowing its density and mass?
You can find the diameter of an asteroid knowing its density and mass by using the formula for volume of a sphere (V = 4/3 * π * r^3, where r is the radius) and density (density = mass/volume). With the asteroid's mass, you can calculate its volume using density, and then find the radius using the volume formula. Finally, double the radius to find the diameter.

How do you work out density of an alloy given its make up?
To calculate the density of an alloy, you would first determine the individual densities of the metals in the alloy. Then, using the mass fractions of each metal in the alloy, you can calculate the overall density of the alloy using a weighted average formula. This formula involves multiplying the density of each metal by its mass fraction and summing those values to get the final density of the alloy.
