Transcribed Image Text: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=39.019 mol
contain 0.2361 grams of potassium and 0.1936 grams of sulphur; the rest was
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 0= 16. 0og/ mot
atomic symbols in the formulas in the order KSo.)
S = 32.079 /mol
