M+ is аn unknоwn metаl cаtiоn with a +1 charge. A student dissоlves 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 0.74 g Mass of filter paper 0.80 g Mass of filter paper plus AgCl precipitate 2.23 g During the course of the experiment, which of the following happens to the NO3- ions?
