A 0.1114 g sample containing chloride, Cl- ion was added with 38.00 mL of 0.03279 M silver nitrate, AgNO3 and after allowing the precipitate to form, the remaining silver was back-titrated with 0.02532 M potassium thiocyanate, KSCN, requiring 25.14 mL to reach the end point. Determine the percentage (w/w) of chloride ion in the sample.

[Given Cl = 35.5 g/mol; Ag = 107.9 g/mol; N = 14.0 g/mol; O = 16.0 g/mol]
