A 4.476 g sample of a petroleumproduct was burnt in a tubefurnace, and the SO2 produced was collected in 3%H2O2. Reaction: SO2(g) +H2O2--> H2SO4. A 25.00 mL portion of 0.00923 M NaOH was introduced into thesolution of the H2SO4, following which theexcess base was back titrated with 13.33 mL of 0.01007 M HCL. Calculate the part per million sulfur in the sample.
