Answer(2) En10Fs40Wo50 Given that, Fe+2= 0.80 Mg+2= 0.20 Ca+2= 1.00 %age of Enstatite (Mg2Si2O6) = (0.20/2) × 100 = 10 %age of Ferrosilite (Fe2Si2O6) = (0.80/2) × 100 = 40 %age of Wollastonite (Ca2Si2O6) = (1.00/2) × 100 = 50 So, the correct mineralogical composition is (Enstatite)10 (Ferrosilite)40 (Wollastonite)50 or, En10Fs40Wo50
