a student used a gravimetric technique to determine the percent chloride in an unknown sample. although the technique differs in details from the one used in the gravimetric determination of sulfate, the results can be calculated in the same manner as in your experiment.
The student precipitated silver chloride as the final product. Upon weighing, she found the mass of silver chloride was 1.0922 g. The original unknown sample was 3.2432 g. Calculate the percent chloride in the unknown.
This question was worded so strangely, that i am just flat out confused. please help me.

Ignore the first paragraph
Calculate mass of Cl in 1.0922g AgCl
Molar mass AgCl = 143.3214 g/mol
Molar mass Cl = 35.453g/mol
mass Cl in 1.0922g AgCl = 35.453/143.3214*1.0922 = 0.270g
Mass of original compound = 3.2432g
% Cl in compound = 0.270/3.2432*100 = 8.33%
