Chapter 6, Problem 107AE

Chlorisondamine chloride (C₁₄H₂₀Cl₆N₂) is a drug used in the treatment of hypertension. A 1.28-g sample of a medication containing the drug was treated to destroy the organic material and to release all the chlorine as chloride ion. When the filtered solution containing chloride ion was treated with an excess of silver nitrate, 0.104 g silver chloride was recovered.

Calculate the mass percent of chlorisondamine chloride in the medication, assuming the drug is the only source of chloride.
