An unknown metal cation has a +1 charge. The bromide of the unknown metal (Metal Br) is dissolved in enough water to make 100mL of solution. The solution is then mixed with an excess of silver nitrate solution to precipitate silver bromide. The precipitate is collected by filtration, dried, and the following data were obtained: Mass of Metal Br = 1.38 g Mass of filter paper = 0.98 g Mass of filter paper and precipitate = 2.86 g Please use the following atomic weights: Br - 80 Ag - 108 N- 14 O- 16
