First step is to calculate the mass of Ag in each compound separately: From the periodic table: molar mass of Ag is 107.87 gm molar mass of Cl is 35.45 gm molar mass of Br is 79.9 gm For AgCl, mass % of Ag = [107.87/143.32] x 100 = 75.26% For AgBr, mass % of Ag = [107.87/187.77] x 100 = 57.45 %
Second step is to calculate the mass % of each compound in the mixture: Assume mass % of AgCl is y and that of AgBr is (1-y) as the total percentage is 100% or 1 0.6094 = 0.7526 y + 0.5745 (1-y) y = 0.8716 This means that the mixture is almost 87% AgCl and 13% AgBr The mass % of chlorine and bromine together is (100%-60.94%) which is 39.06% mass % of chlorine = (1-0.6094)(0.8716) x 100 = 34.044% mass % of bromine = 39.04 - 34.044 = 5.056%
The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.
