WebThe concentration of a solution is basically a measurement of solute (B) with respect to the solution(S) or solvent(A). It is the number of moles of solute per liter of solution, which can be calculated using the following equation: Molarity = mol solute/L of solution. It measures the quantity of a substance per unit volume.
