a solution of an unknown metal chloride (0.8870 g) was treated with silver nitrate to yield (1.9132 g). calculate the percentage by mass of chloride in the unknown chloride
You obtained 1.9132 g AgCl. Convert that to grams Cl. The easy way to do that is to multiply by a chemical factor to do the conversion. (I don't think chemical factors are taught anymore since there are other ways to do it).
1.9132g AgCl (atomic mass Cl/molar mass AgCl) = xx g
%Cl = (xx g/mass sample)*100 = ?
