Question

Calculate the amount (volume) of 6.25% (wt./vol.) NaOCl solution (commercial bleach)
required to oxidize 150 mg of 9-fluorenol to 9-fluorenone. Whenever appropriate, use
balanced chemical equations as a part of your calculation.

Any help is appreciatede.

Answer 1

Do you go to UCI by any chance? Anyway, this is how the TA helped me:

6.25% w/vol
1000 g/L

62.5 g/L

150 mg/ 182.2 = 0.82 mmol x 74 (the NaOCl MW) = 60.92 mg

62.5 mg/mL x (x)mL = 60.92 mg

60.92 mg/ 62.5 = 0.97 mL which is roughly 1

and we know that our calculation is correct because the procedure asks for 1.2 mL, so it's fairly close!

Hope that helps!!

Answer 2

I go to UCI, and this helped a lot. Thank you!
