Definition

The amount of a substance (solute) in a given volume of liquid (solution), measured in moles per liter.

Example

The molarity of the salt solution was calculated to be 0.5 moles per liter.

Conversation

Hey, do you remember learning about molarity in chemistry class?

Yes, it was a bit confusing at first, but I got the hang of it eventually.

Right? It's all about how many moles of solute are in a liter of solution.

Exactly! Once you grasp that, it makes solving problems way easier.

Root Explanation

Molarity → It is formed from "mole" (from Latin *moles*, meaning mass or bulk) and "-arity" (a suffix used in chemistry to denote a property or condition). The word "molarity" refers to the condition of a solution expressed in terms of the number of moles of solute per liter of solution.

Memory Tip

Think of 'mole' as a measure of mass in chemistry, and '-arity' as indicating a specific property. This helps you remember that molarity is about the concentration of a solution in terms of moles.
