What is Molarity?
Molarity (M) is the most common measure of solution concentration, defined as the number of moles of solute dissolved per litre of solution (mol/L). It is used to calculate the amounts of reactants and products in solution reactions. Molarity changes with temperature (as volume changes), which is a limitation compared to molality for precise thermodynamic calculations.
