Can anyone help me with a molarity problem?

True or false? To prepare 20.0 mL of a 2.00 M solution of hydrochloric acid from a 10.0M stock solution, you should take 4.00 mL of the stock solution and add 20.0 mL of water. If true, verify with calculations. If false, explain why(including calculation) and state how to correctly make the desired solution.
