A Sample of Au(ClO)3 is contaminated with LiClO. An acidified 0.2000g sample of this mixture is treated with excess sodium iodide and subjected to iodometric titration. The sample requires 48.24 mL of 0.08893 mol/L Na2S2O3 to reach the equivalence point. Assuming that the Au3+ and Li+ ions are unreactive during titration, determine the ass percent of LiClO sample.
