Question - The amount of sulfuric acid produced can be determined by titration with sodium hydroxide of known concentration. An 666.0 gram sample of an air that is known to contain sulfur dioxide was reacted with excess hydrogen peroxide. Given that 18.50 mL of a 0.00250 M NaOH(aq) were required to neutralize the H2SO4(aq) produced, calculate the mass percentage of SO2(g) in the air sample.H202(aq)+SO2(g)--->H2SO4(aq)
