how many grams of NaOCl are in 12.14 mL of a 6.65% (wt./vol.) NaOCl solution?
Please help me set this up... I have no idea what to do.

I would try setting it up as a proportion. The percentage just means that there are 6.65 grams of NaOCl per 100 grams. Therefore, set up the problem of (6.65/100)=(x/12.14)
