Prepare solutions of HCl

[palimmo]

Hi!

Yesterday I prepared 1 L of HCl 1M.

Today, using that liter, I need to prepare 100ml of 0.5M, 100ml of 0.1 M e 100ml of 0.01 M.

So:
- for the 0.5 M I can use 50 ml of 1M and 50 ml of distilled water?
- for the 0.1 M I can use 10 ml of 1M and 90 ml of distilled water?
- for the 0.01 M I can use 1 ml of 1M and 99 ml of distilled water (or 10 ml of 0.1 M and 90 of distilled water)?


Thanks in advance!!!
