A student obtained a vial of powder consisting of a mixture of iron (III) chloride hexahydrate (FeCl_3-6H_2O) and silver nitrate (AgNO_3) in unknown proportions. He weighed the vial with the powder in it and found the mass to be 20.560 g. He then poured the powder into a beaker and found the mass of the empty vial to be 15.723 g. Water was added (500 mL) to powder in the beaker, and the contents were mixed and heated for 15...
