A 1.4639-g sample of limestone was analyzed for Fe, Ca, and Mg. The iron was determined as Fe>O3 (MM: 159.67), yielding 0.0357 g. Calcium was isolated as Caso4 (MM:136.11), yielding a precipitate of 1.4058 g, and Mg was isolated as 0.0672 g of Mg2P207 (MM: 222.49). Report the amount of Fe as %w/w Fe2O3, Ca as %w/w Cao (MM: 56.07), and Mg in the limestone sample as %w/w Mgo (MM: 40.3). Write your answers here or you may do option 2. Option 2. Attach your solution as pdf or jpeg and make sure that it is readable. If you can't attach it here, you may send it in messenger privately or via email with subject, FAM name - Quiz 4.
