The purity of a pharmaceutical preparation of sulfanilamide, C6H4N2O2S, can be determined by oxidizing the sulfur to SO2 and bubbling the SO2 through H2O2 to produce H2SO4. The acid is then titrated with standard NaOH. Calculate the purity (%w/w sulfanilamide) given that 1.457 g of the sulfanilamide sample required 20.6 mL of 0.3443 M NaOH. (Note: 1 mol sulfanilamide = 1mol S = 1mol H2SO4)
