An aqueous solution of a metal nitrate (MNO₃) and Cl₂ gas was produced when a sample of a metal chloride (MCl) weighing 7.668 g was treated with 92.70 mL of 1.000 M nitric acid (HNO₃). The solution was boiled to get rid of all the dissolved Cl₂ gas. The solution was then titrated with 0.2000 M KOH. Determine the identity of the metal M if 196.0 mL volume of KOH was required to neutralize the excess HNO₃.
