If 2.0 ml of 0.010 M of NaOH is mixed with enough water to make the total volume 8mL, what is molarity of the resulting solution?

**DrBob222**, Thursday, March 15, 2012 at 5:51pmThere are numerous ways to do this but the shortest way is to use the dilution formula that you have in the last sentence of your post.

I even take a short cut with that.

0.01M NaOH x (2.0 mL/8 mL) = ? M.

Note: It isn't needed, but you really do have the mass.

moles NaOH = M x L = ?

Then mols NaOH = grams NaOH/molar mass NaOH.

Knowing mols NaOH and molar mass you can calculate grams.
