Calculate the Molarity of the resulting solution. A sample of NaNO3 weighing 8.50 grams is placed in a 500. ml volumetric flask in addition to distilled water was added to the mark on the neck of the flask. Calculate the Molarity of the resulting solution. 1. Convert the given grams of solute to moles of solute : 2. Convert given ml of solution to liters 3. Apply the definition as long as Molarity: Molarity = moles NaNO3 / volume of the solution in liters
