question 136

Multiple Choice

Suppose you are studying coordination compounds of Co(II) with the ligand pyridine (py,C₅H₅N,molar mass = 79.10) .You isolate a crystalline compound,and since the only available anions are Cl^- and NO₃^-,you hypothesize the empirical formula of the coordination compound must be Co_w(py) _x(Cl) _y(NO₃) _z.
-You discover that the complex decomposes in water.You dissolve 0.1000 g of the complex in H₂O and add excess NaHg(SCN) ₄,which precipitates Co(II) as CoHg(SCN) ₄(s) .After the precipitate is washed and dried,its mass is 0.1102 g.How many grams of cobalt are contained in 0.1000 g of the complex?

• A)0.1102
• B)0.0396
• C)0.0132
• D)0.437
