mols NaOH = M x L = ?
1 mol NaOH = 2 mol ascorbic acid
g ascorbic acid = mols x molar mass
%asc = (g asc/mass sample)*100 = ?
Ascorbic acid (vitamin C) is a diprotic acid having the formula H2C6H6O6. A sample of a vitamin supplement was analyzed by titrating a 0.3252 g sample dissolved in water with 0.0284 M NaOH.
