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 student then mixes the solution with excess agno3 solution, causing agcl to precipitate. the student collects the precipitate by filtration, dries, it and records the data shown below. (the molar mass of agcl is 143 g/mol.) mass of unknown chloride, mcl mass of filter paper mass of filter paper plus agcl ppt 0.42 g 1.00 g 2.43 g find the identity of metal chloride. (a) lithium chloride (b) sodium chloride (c) magnesium chloride
