4. Silicаte Minerаl Cоmpоsitiоn (10pts Totаl): In pyroxene, Mg-end member Enstatite (MgSiO3) and Fe-end member Ferrosilite (FeSiO3) form a solid solution, (FexMgx)1SixO3. Chemical composition of a pyroxene mineral is given in the table below in weight percent (wt%) and molar fractions of component oxides. Components wt% Molar mass Molar fraction MgO 30.22 40.30 0.75 FeO 13.47 71.84 0.19 SiO2 56.31 60.08 0.94 A) (15pts) Determine the chemical formula of this pyroxene in the correct format (FexMgx)1SixO3 using the steps from M2A. SHOW all steps….on the supplemental document supplied piece of paper and put a box around your determined chemical formula, which will be uploaded after the exam is complete (see instructions)! Enter mole ratio for each element composing the mineral in the space below (rounded to one significant figure. Each answer composed of two numbers and a decimal point (For example: 2.3 or 4.0 or 0.6). Mg [1] Fe[2] Si [3] O [4]
