A sample conaining both HCl and HNO3 had a density of 1.083g/ml. A 30.00 ml amount of this sample required 25.78 ml of 0.3248 M NaOH for titration. Another 30.00 ml amount of this sample required 24.47 ml of 0.1327 M AgNO3 for titration. Calculate the mass percent of HNO3 (molar mass = 63.018 g/mol) in the sample.
