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
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 wasn't 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?
