1cm/3= 1000dm/3 (since 10^3=1000)
1dm=1L

You started with the wrong assumption, so this is wrong as well. Note that 1cm/3 and 1cm3 are two different things. I suppose you wanted to write cm^3.
And miraculously this is correct.
A density of 1.5 g cm-3 means that for every cubic centimeter of a substance, there is a mass of 1.5 grams. This is a measure of how tightly packed the particles of a substance are.
Density is measured by dividing the mass of a substance by its volume. The units for density are typically grams per cubic centimeter (g cm-3) or kilograms per cubic meter (kg m-3).
A density of 1.5 g cm-3 is considered a relatively high density. For comparison, the density of water is 1 g cm-3 and the density of air is approximately 0.0012 g cm-3.
Density is an important physical property of a substance that can affect its other properties such as buoyancy, solubility, and melting point. Substances with higher densities tend to be more dense and sink in water, while substances with lower densities will float.
Yes, density can change depending on the conditions of temperature and pressure. For example, as water freezes, it expands and becomes less dense, causing it to float on top of liquid water. Additionally, substances can be compressed or expanded, which can also change their density.
