Question

what volume of water must be added to 10ml og 6.0M NaOH to make a solution that is .30 M in NaOH

How do I solve for this

Answer 1

Lets see. You want to dilute it 20x, so add nineteen parts water to one part sodium hydroxide.

Isn't that 190ml water, 10 ml of NaOH?

Check that. You can check it by calculating the molarity of the resulting solution.

Answer 2

3.97m
