How is molarity defined?

Molarity is defined as the concentration of a solute in a solution, specifically measured in moles of solute per liter of solution. This definition captures how much of a substance is dissolved in a given volume of solvent, allowing for straightforward calculations and comparisons in chemical reactions. Molarity is a fundamental concept in chemistry because it provides a clear understanding of how concentrated a solution is, which is crucial for stoichiometric calculations when performing experiments or reactions.

The concept of molarity is particularly valuable because it relates moles, a fundamental unit in chemistry for quantifying substances, to volume. This allows chemists to easily scale reactions and predict outcomes based on the concentrations of reactants.
