Armed with a validated method for determining the molar mass of a metal ion (in the form of a metal carbonate), you now set out to identify the metal ion in the unknown metal carbonate. You weigh out 0.2473 g of the unknown metal carbonate, add 20 mL of DI water, add a drop of methyl red indicator solution and then titrate the sample with 36.99 mL of the 0.1081 M HCl solution. Write a balanced chemical equation for the reaction (you can represent the unknown metal as M) and answer the following questions: a) Calculate the molar mass of the unknown metal carbonate: g/mol b) Calculate the molar mass of the unknown metal: g/mol c) Enter the chemical symbol of the unknown metal
