(a) If you started with 1.21 g of 3-nitrophthalic acid and had a 88% yield of 3-nitrophthalhydrazide, how many grams of 3-nitrophthalhydrazide were recovered? Be sure to show your work. (5 pts)
(b) Based on the quantity of 3-nitrophthalhydrazide from above (a) how many grams of sodium dithionite would you need to perform the synthesis of luminol assuming you need 1.3 equivalents of reducing agent in the reaction. Be sure to show your work. (5 pts)
