How to dilute 100 mM to 5 mM?

Answer 1

Dilute a measured volume of the 100 mM solution with 19 times its own volume of pure water to produce a 5mM solution.

Answer 2

To dilute a 100 mM solution to 5 mM, you would need to dilute it by a factor of 20. To do this, you can add 19 parts of a suitable solvent (such as water) to 1 part of the 100 mM solution. Mix thoroughly to ensure a homogeneous 5 mM solution.
