6-20. A 4.476-g sample of a petroleum product was burned in a tube furnace, and the SO, produced was col- lected in 3% H,O2. Reaction: SO,(g) + H,O, →H,SO4 A 25.00-mL portion of 0.00923 M NaOH was intro- duced into the solution of H,SO,, following which the excess base was back-titrated with 13.33 mL of 0.01007 M HCI. Calculate the parts per million of sulfur in the sample.
