Silver Nitrate Is Commonly Used to Determine the Chloride Ion $\rightarrow$

Silver nitrate is commonly used to determine the chloride ion concentration in an aqueous solution.37.0 mL of 0.174 N AgNO₃ is required to titrate the chloride ion in a 20.0 mL sample of zinc chloride solution.What is the normality of the zinc chloride? 2 AgNO₃(aq) + ZnCl₂(aq) $\rightarrow$ 2 AgCl(s) + Zn(NO₃) ₂(aq)

A) 0.0470 N
B) 0.0941 N
C) 0.161 N
D) 0.322 N
E) 0.644 N
