How to prepare glycine stock solution of 0.2 m?

Answer 1

The molecular weight of glycine is 75.06

So for 50 ml of 0.2M glycine solution,

Weigh 0.75 gram of glycine, and add 50 ml of DI water.

Answer 2

To prepare a 0.2 M glycine stock solution, weigh out 7.52 grams of glycine (molecular weight = 75.07 g/mol) and dissolve it in enough distilled water to make a final volume of 100 mL. Stir the solution until the glycine is fully dissolved. Label the container properly and store it at the appropriate temperature.
