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.
PART 1 - You prepare a solution of sodium chloride (NaCl) in water to a specified molarity. PART 2 - You obtain a different sodium chloride solution, whose molarity is also known, and you calculate the mass of NaCl contained in a 25.0 mL sample of the new solution.You then measure out this volume, and remove the water from the solution to see if it actually contains the amount of NaCl you calculated.art 2 â Determining the Mass of NaCl in a 25.0 mL Sample of a Solution with Known Molarity. In Part 2, you obtain a different NaCl solution and you calculate the mass of NaCl solution contained in a 25.0 mL sample of the solution.
