∙ 11y agoPure substances are those with nearly all molecules identical, or those with a network structure which consists of nearly all repetitions of the same few atoms.
A perfectly pure substance is never achievable, but specifications for pure substances range between 90% and 99.9999%.
Anything else is a mixture -- mixtures involve 2 or more substances, and are divided into homogeneous (a sample will contain reliably constant proportions of the substances) or heterogeneous (which are "lumpy" so that a sample might be predominantly one sort of pure substance, and another might be quite different).
