Calculate the percentage composition, by weight, in terms of the constituent oxides of the following minerals. Constituent oxides are SiO2, Al2O3, TiO2, FeO, MgO, Na2O, K2O, CaO, H2O, etc. Also, write a balanced chemical equation for each mineral.
a. Ilmenite {FeTiO3}
b. Muscovite {KAl2(AlSi3O10)(OH)2}
c. Plagioclase feldspar (albite) {NaAlSi3O8}
d. Magnetite {Fe3O4}
e. Olivine {(Mg,Fe)2SiO4 - assume equal proportions of Mg and Fe}
