Can someone please help with a percent yield??
« on: March 21, 2010, 10:48:30 AM »
I have no idea how to do this.

3-nitrophthalic acid (NO4C8H5) + Hydrazine (N2H4) ---> 5-Nitrophthalhydrazide (N3C8H504) --> Luminol (C8H7N3O2)

We used 0.30 grams 3-nitrophthalic acid  211.13 g/mol
0.4 mL hydrazine  32.05 g/mol
then used 1.3 mL sodium hydroxide and .8g sodium dithionite

The final yield was 0.33 grams of luminol

I know I have to find the limiting reagent which I believe is the 3-nitropthalic acid, but I am not sure how to show the entire calculation and set it up.  Any help is appreciated!  Thanks!
