Compounds/Gram Formula/Percent Composition

Materials composed of two or more phases wich are separated by definite boundaries called interfaces.
Any material composed of two or more kinds of matter, each keeping its own characteristic properties, can be mixed in varying proportions and can be separated by mechanical means.
Those materials which are uniform in composition, each part has identical properties, and consists of a single phase.
Substances composed of only one kind of atom and cannot be further deocomposed by ordinary chemical means.
