Molarity vs molality WebFor the third solution, we are given the amount of NaCl as 0.0420 mol and the final volume as 6.50 mL. We need to convert the volume to liters before we can use the formula: Volume = 6.50 mL = 0.0065 L. Now we can calculate the molarity: M = 0.0420 mol / 0.0065 L M = 6.46 M. Therefore, the molarity of the solution is 6.46 M.
