Answer to Question #73417 in General Chemistry for Annaliesse Reyes

Question

A mixture consisting of only lithium chloride (LiCl, 42.391 g/mol) and potassium chloride (KCl, 74.55 g/mol) weighs 1.7695 g. When the mixture is dissolved in water and an excess of silver nitrate is added, all the chloride ions associated with the original mixture are precipitated as insoluble silver chloride (AgCl, 143.32 g/mol). The mass of the silver chloride is found to be 5.3686 g. Calculate the mass percentage of lithium chloride in the original mixture.
