Because I'm apparently retarded now by not taking chem right after grade 12...

Assuming a density of 1.055 g/mL, what is the mass % NaOCl in a full-strength bleach solution that is 0.62 M NaOCl?

What I figured to do was...

0.62M NaOCl x 74.441g/1mol NaOCl = 46.15342g NaOCl

From here I have no idea what to do with the density.

I thought of doing this....

46.15gNaOCl x 1mL/1.055g = 43.7ml

But then I have no idea what to do then....
