The mass of each element changes into moles by taking the molar mass from the periodic table as follows:
Each mole is divided by the smallest number of calculated moles and taken round to the nearest whole number.
The value of each element is considered as the mole ratio of the elements, which is represented by subscripts in the empirical formula, as follows:
c) Plausible structure for
