Question

M+ is an unknown metal cation with a +1 charge. A student dissolves the chloride of the unknown metal, MCl, in enough water to make 100.0 ml of solution. The students then mixes the solution with excess AgNO3 causing an AgCl to precipitate. The student collects it by filtration, dries it, and records data: mass of unknow MCl = 0.74 g, mass of filter paper = 0.80g, mass of filter paper plus AgCl precipiate = 2.23g. What is the identity of the metal chloride?
