help asap A sample containing both HCl (FW 36.45) and HNO3 (FW 62.98) had a density of 1.083 g/mL. A 10.00-mL aliquot of this sample required 25.29 mL of 0.1163 M NaOH for titration. Another 10.00-mL aliquot of the sample required 20.75 mL of 0.1216 M AgNO3 for titration. Calculate the % HNO3 in the sample.
