A 1.268 g sample of an alkaline earth metal carbonate, MCO3 was treated with 100.00 mL of 0.2166 M HNO3, as shown in the reaction below. After the reaction, it was determined that 8.809 × 10－3 moles of HNO3 remained in solution. Given this information, what is the identity of the metal M? Show all of your work.

MCO3(s) + 2HNO3(aq) → M(NO3)2(aq) + CO2(g) + H2O(l)
