Calculations

If 1 mmole = molecular weight (mg) then 10 mmoles of NaOH is 400 mg or 0.4 g of NaOH. You would weigh it out and dissolve in ~ 150 mL of water. Once it is in solution make it up to 200 mL. ... To interconvert between concentration expressed in molarity and weight per volume units you need to use the molecular weight. ................
