To a sample of alkaline earth metal carbonate (MCO3; 0.250 g) was added 15.0 mL HCl (0.500M). Carbon dioxide gas evolved out from the solution. After the reaction was completed. The solution was back titrated with a NaOH solution (33.50 of 0.1500 M).(a) Write the reaction equation of MCO3 and HCl; (b) Calculate the Molecular Mass of MCO3. (c) Determine what is this sample: CaCO3; MgCO3; or BaCO3?Thank you in advance.
