8. Potassium persulphate (Anthion) is used in photography to remove the last traces of hypo from photographic papers and plates. A 0.8162 gram sample was found to k: 39 contain 0.2361 grams of potassium and 0.1936 grams of sulphur; the rest was s = 32.0 oxygen. The molecular mass of this compound was measured to be 270.3 u. What are the empirical and molecular formulas of potassium persulphate? (Arrange the atomic symbols in the formulas in the order KSO.)
