Solution Preparation (Çözelti Hazırlama)

How do I make __ mL of a __ molar solution? Ex: How do I make 100 mL of a 3M aqueous sodium hydroxide solution? Determine molarity required: M = 3M solution = 3 moles NaOH/1 L of solution Determine molar mass: MM of NaOH = 40 g/mol Convert volume required to liters: V = 100 mL x 1 L/1000 mL = 0.1 L Grams required = V x M x MMNaOH 0.1 L soln x 3 moles NaOH/1 L soln x 40 g NaOH/1 mole NaOH = 12 g NaOH Prepare the solution: Select a 100-mL flask, preferably volumetric. Weigh out 12 grams of sodium hydroxide. Fill flask about half full with deionized or distilled water. Add sodium hydroxide to the flask. Mix until dissolved using a stirring bar and stir plate or by swirling gently. Add water up to the 100-mL volume mark on the glassware and mix again.
