It is often used with abstract concepts, liquids, grains, and other materials or qualities that are seen as a whole rather than in individual parts.

Conversely, “number of” is used with countable nouns, emphasizing the capability to count the items or entities individually. Recognizing and applying this distinction enhances the precision and clarity of language, particularly in writing and formal communications.

Commonly Asked Questions
