• Oct 27, 2025 1 Molar To Mmolar units. Example 3: You have 100 mL of a 2 M stock solution of sodium hydroxide (NaOH) and want to dilute it to a final volume of 500 mL. What is the final concentration in mM? First, use the dilution formula to find the final molarity: (2 M)(100 mL) = M₂(500 mL) M₂ = 0.4 M Th By Crystal Barrows
