You have a 12 M solution of hydrochloric acid. How many milliliters of this solution will give 25.0 mL of 2.0 M hydrochloric acid when diluted?
Where to start, and Where to end. The process of figuring this problem would be greatly appreciated.

you want to dilute it by a factora of six, so you add 5 parts water, one part original HCL.
one part is 25ml, so add five parts (125ml) water to give 150ml 2M HCl 
calculate the grams of hydrochloric acid that must be diluted to a volume of 8 liters to produce a concentration of .25 moles
