Homework Help: CHEMISTRY

Posted by amy on Tuesday, April 10, 2007 at 8:36am.

How many moles of NAOCl are there in 3mL of bleach solution. The density of the solution is 1.005g bleach soln/mL and it is 5.25% by mass (5.25 NAOCl/100g soln.

Can someone tell me if I have this set up correctly?

3mL * 1.005g/1ml * 5.25g/100g* 1mol NAOCl/74.44g NAOCl

Thank you

I think that looks OK

....be consistent with mL or ml

....remember it is NaOCl

....and there is a space between the number and the unit.

but Hey I'm picky



Thank you I just wasnt sure I had the problem set up correctly. I appreciate the input. My professor is a bit picky as well :)

I learnt to be picky as a Prof myself, perhaps it goes with the job?

Good luck.
