Molarity is the term used to describe the concentration of a solution. In other words, it is the number of moles of solute dissolved in 1 litre of solution.
A mole is a unit of measurement for a chemical substance. Molarity emerged from mole, coined by German chemist from Molekul which means molecule.
Molarity (M) = Moles of solute/Litres of solution
Where, solute is the substance dissolved, solvent is the substance where the solute is dissolved (usually water) and the solution is the combination of both solute and solvent. Molarity Equation examples:Example 1. Find the Molarity of a solution where 1.56 moles of sugar is dissolved in 2.79 L of solution?
Answer: Molarity (M) = Moles of solute / Litres of solution Molarity (M) = 1.56 moles of sugar / 2.79 L of solution = 0.559 moles/L
