How much water must be added to make 500 ml of 12.0 M HCl to 1.0 M HCl

(500mL• 12M) / 1.0M
=6000m

Is this correct?

1 answer

What's 6000m. Did you mean 6000 mL? That is the TOTAL volume needed; the question wants to know how much must be ADDED so you must add 6000 mL - 500 you already had = 5500 mL to be added.
