Answers are for informational purposes only. Please confirm any information given with your own doctor. If I don't respond right away, be patient.

You're going to dilute the 1 M HCl in water to get a less concentrated 0.25 M HCl. First determine the amount of moles in the final 10 mL 0.25 M HCl.

10 mL = .01 L × .25 moles/L = .0025 moles HCl

Now you work backwards with the concentrated solution.

1 mol/L × (volume) = .0025 moles HCl
Volume = .0025 liters = 2.5 mL

You need to prepare a 10 mL aqueous solution containing 2.5 mL of 1 M HCl.

Please don’t click “bad” or “poor” service as this leaves negative feedback for me. If you aren’t 100% satisfied or have more questions, click “reply” instead.
