Addition of AgNO₃ to Aqueous Solutions of the Complex Results $\times$

Multiple Choice

Addition of AgNO₃ to aqueous solutions of the complex results in a cloudy white precipitate,presumably AgCl.You dissolve 0.1000 g of the complex in H₂O and perform a precipitation titration with 0.0500 M AgNO₃ as the titrant.Using an electrode that is sensitive to [Ag⁺],you reach the endpoint after 9.00 mL of titrant are added.How many grams of chloride ion were present in the 0.1000-g sample?

A) 4.50 $\times$ 10^-4
B) 5.00 $\times$ 10^-3
C) 1.77 $\times$ 10^-3
D) 6.38 $\times$ 10^-2
E) 1.60 $\times$ 10^-2
