Example

The osmolarity of the saline solution was carefully measured to ensure proper hydration.

Conversation

Have you ever heard of osmolarity in biology class?

Yeah, it's about how concentrated a solution is, right?

Exactly! It's usually measured in osmoles per liter.

That makes sense, especially when studying fluids in the body.

Root Explanation

Osmolarity → It is formed from "osm-" (from Greek "osmos", meaning push or thrust) and "-larity" (from Latin "laritas", meaning quality or state). The term osmolarity refers to the quality or state of a solution's osmotic pressure, which is influenced by the number of solute particles in a solution.

Memory Tip

Think of 'osmos' meaning 'push' to remember that osmolarity relates to the 'quality' of how solutions exert pressure based on their solute particles.
