Calculate the percentage composition, by weight, in terms of theconstituent oxides of the following minerals. Constituent oxidesare 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 andFe}
