Calculate the weight percentage of chloromycetin in the sample

Chloromycetin is an antibiotic with the formula C11H12O5N2CL2.  A 1.03-g sample of an phthalmic ointement contining choloromycetin was chemically treated so as to convert its chlorine into Cl~ ions.  The Cl~ was then precipitated as AgCl.  If the AgCl weighed .0129g, calculate the weight percentage of chloromycetin in the sample.
