The copper in a 0.2500–gram sample of copper ore is treated in solution with excess
potassium iodide and the liberated iodine titrated with 16.50 mL of sodium thiosulfate
(1.000 mL ≈ 0.003619 grams potassium bromate). What is the purity of the ore expressed
in terms of percentage of cuprous sulfide?
