gavimetric analysis
A 1.4639g sample of limestone was analyzed for Fe, Ca, and Mg. The iron was determined as Fe2O3, yielding 0.0357g. Calcium was isolated as CaSO4, yielding aprecipitate of 1.4058g, and Mg was isolated as 0.0672g of Mg2P2O7. Report the amount of Fe, Ca and Mg in the limestone sample as % Fe2O3, %CaO and %MgO.
