A 4.476g sample of a petroleum product was burned in a tube furnace, and the SO2 (MM 64.07g/mol) produced was collected in 3% H2O2 (MM 34.02g/mol).
Reaction:SO2(g) + H2O2 -----> H2SO4
A 25.00mL portion of 0.00923M NaOH (MM 40.00g/mol) was introduced into the solution of H2SO4 (MM 98.08g/mol), then the excess was back titrated with 13.33mL of 0.01007M HCl (MM 36.46g/mol). Calculate the parts per million of sulfur in the sample.
