The mineral is pyroxene.1. recalculate the analysis into chemical formula.The formula should show the atoms of each element in a formula that has 6 oxygen atoms.A) start with the column showing the weight percent elements. Deal with AL-2O3, Na2O, K2O, and Fe2O3 such that your oxide factor converts the oxide into a single element.Ignore the water. Calculate the w% oxygen (total-weight% of the other elements) and add oxygen to the list of w% elements. In the next column calculate the atomic proportions. Divide the element w%s by elemental atomic weights.Remember to include oxygen.Calculate the multiplication factor needed to convert the proportion of oxygen to 6 atoms. In the next column multiply the atom. proportions of the elements by this factor.This gives the atomic proportion the elements relative to 6 atoms of O. Write out the structural formula.
