Analysis: Narke Samfurin a cikin 80 ml na cakuda 100 ml na glacial acetic acid da 300 ml na acetic anhydride ta hanyar motsawa, da titrate tare da Titrant.Yi lissafin kashi na Adenine (C5H5N5) a cikin ɓangaren da aka ɗauka:
Sakamako = [(V - B) × N × F × 100]/W
V = Samfurin titrant girma (mL)
B = Ƙarar titrant (mL)
N = daidaitaccen titrant (mEq/ml)
F = daidaitattun ma'auni, 135.13 mg/mEq
W = Nauyin Samfurin (mg)
