To calculate molarity. 1  Find the number of moles of solute dissolved in solution. 2  Find the volume of solution in liters. 3  Divide moles solute by liters solution.ample Molarity Calculation. Take the following example: Calculate the molarity of a solution prepared by dissolving 23.7 grams of KMnO 4 into enough water to make 750 mL of solution. This example has neither moles or liters needed to find molarity. Find the number of moles of the solute first.
1 Determine the moles of unknown (the solute) from the molality of the solution and the mass of solvent (in kilograms) used to make the solution. 2  Determine the molar mass from the mass of the unknown and the number of moles of unknown. Determine the molar concentration of the unknown in the solution from the observed osmotic pressure. 2  Determine the moles of unknown (the solute) from the molarity of the solution and the volume (in liters) of the solution. 3  Determine the molar mass from the mass of the unknown and the number of moles of unknown.
