Although silver chloride is insoluble in water, adding ammonia to a mixture of water and silver chloride causes the silver ions to dissolve because of the formation of [Ag(NH₃)₂]+ ions. What is the concentration of [Ag(NH₃)₂]+ ions that results from the addition of excess ammonia to a mixture of water and 0.022 g silver chloride if the final volume of the solution is 150 mL?
