How can the composition of an object be determined using density?
If you had an object whose composition was entirely unknown, you could not analyse its composition by density alone. There are an endless number of possible combinations of materials that would have any given density. However, in some circumstances density does allow you to determine composition. If for example, you have an alloy of copper and zinc, but you do not know the relative proportion of the two metals and you would like to find out, you could determine that proportion by measuring the density, since copper and zinc each have a different density, and the problem can be solved as a simple algebraic equation.
