Suppose you have a 40.3 mL sample of a solution containing a mixture of nitric acid (HNO3?) and hydrochloric acid (HCl). The concentration of hydrogen ions in this solution is 0.241 M. When you add an excess of silver nitrate to the solution, 0.823 g of silver chloride (AgCl) precipitate. What was the molar concentration of HNO3 in the original solution?
