Approx...
Explanation:
Under FIERCE heat, you could thermally decompose magnesium carbonate...(of course, you COULD add acid to the salt!)..
Now there is a 1:1 molar relationship between the metal carbonate and carbon dioxide...we use
And given the stoichiometry, we generate 1 equiv carbon dioxide gas...
Are you happy with this?
Alternatively, we could treat the carbonate with 2 equiv hydrochloric acid...
