SOLVED: A geologist discovers magnesium carbonate hydroxide hydrated salt with the chemical formula MgCO3·OH·nH2O. The geologist determines that the original hydrated sample weighs 201 g. After heating the salt to its anhydrous form, it weighs 790 g. How many waters of hydration are present in the original hydrated salt? Round your answer to the nearest whole number.Note that this is an entirely fictitious compound and the charges may not balance properly. It is only for demonstrative purposes

SOLVED: The equilibrium concentration of carbonate ion in saturated magnesium carbonate solution is

20.0 mg of a magnesium carbonate sample decomposes on heating to give carbon dioxide and 8.0 mg magnesium oxide. What will be the percentage purity of magnesium carbonate in the sample? [Atomic weight of Mg = 24 ]
