Before it was banned in the 1970s due it its non-selective toxicity, thallium (1) sulfate, TI2SO4 (s), was the active ingredient in some pesticides. A chemist measured 100.0 mL of a solution of thallium (1) sulfate and added excess aqueous potassium iodide to precipitate yellow thallium (I) iodide, TII (s). The mass of the dry precipitate was 2.45 g. Find the molar concentration of the thallium (I) sulfate solution. M(TII) = 331.3 g/mol %3D Tl2SO4 (aq) + 2KI (aq) → K2SO4 (aq) + 2TII (s)

Question
Before it was banned in the 1970s due it its non-selective toxicity, thallium (I) sulfate, Tl2S04 (s), was the active ingredient in some pesticides. A chemist measured 100.0 mL of a solution of thallium (I) sulfate and added excess aqueous potassium iodide to precipitate yellow thallium (I) iodide, TII (s). The mass of the dry precipitate was 2.45 g. Find the molar concentration of the thallium (I) sulfate solution. M(TII) = 331.3 g/mol %3D Tl,SO4 (aq) + 2KI (aq) → K2SO4 (aq) + 2TII (s)
