A 21.0054 g sample of impure magnesium carbonate was heated to complete decomposition
according to the equation
MgCO3(s) → MgO(s) + CO2(g) .
After the reaction was complete, the solid
residue (consisting of MgO and the original
impurities) had a mass of 19.0732 g. Assuming that only the magnesium carbonate had
decomposed, how much magnesium carbonate was present in the original sample?
