5M NaCl

From Protists

How to make 5M NaCl:

• 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 NaCl=58.5 and the molarity=5

• So, if you are making 150mL of 5M NaCl:

      x = (5M)(58.5)(.15L) = 43.875g NaCl

• Now that you've down the math (continuing with values from example):

      1. Fill up container with 150mL of DI water
      2. Weigh out 43.875g of NaCl
      3. Add NaCl to container and mix well
