1. A metal with unknown identification, M, was found to react with nitric acid with the following stoichiometry: 2 HNO3(aq) + M(s) → M(NO3)2(aq) + H2(9) Several trials of varying masses of the metal M were reacted with 100.00 mL of 0.402 M HNO3. From this data, determine the identity of the unknown metal. (Hint: think about which reactant is limiting in each of these trials and how that could help identify the metal by determining the molar mass of the metal.)
