Question

A 6.70 g sample of a binary mixture of silver (I) nitrate and sodium nitrate is completely
dissolved in water to make a solution. Aqueous barium chloride is then added to this solution
in excess to form 3.60 g of silver chloride solid. What is the percent by mass of silver nitrate
in the initial binary mixture?

Answer 1

Ag^+ + Cl^- ==> AgCl

mols AgCl = grams/molar mass =?
? mol AgCl = mols Cl^- = mols Ag^+ = mols AgNO3.
g AgNO3 = mols AgNO3 x molar mass AgNO3
%AgNO3 = (g AgNO3/mass sample)*100 = ?

Answer 2

Thank you!
