1M NaOH

From Protists

How to make 1M NaOH:

  • The equation for molarity is: 
      Molarity= (x grams/ atomic mass) x (1/ # Liters)
      or, x grams = (1M)(atomic mass)(Liters)
  • In this case, the atomic mass of NaOH=40 and the molarity=1
  • So, if you are making 200mL of 1M NaOH: 
      x = (1M)(40)(.2L) = 8g NaOH
  • Now that you've down the math (continuing with values from example): 
      1. Fill up container with 200mL of DI water
      2. Weigh out 8g of NaOH
      3. Add NaOH to container and mix well
