[tex]M _{AgCl =A_{Ag} +A_{Cl} =108+35,5=143,5
adica 1 mol AgCl =143,5 g deoarece a+b=100-60,94 = 39,06
M_{AgBr} =A_{Ag} +A_{Br} =108+80=188
adica 1 mol AgBr = 188 g
143,5 g AgCl ..............35,5 g Cl
x g AgCl.............a g Cl
unde x=143,5a / 35,5
188 g AgBr.......80 g Br
y g AgBr ....b g Br
unde y=188b/80[/tex]
[tex] \left \{ {{x+y=100} \atop {a+b=39,06}} \right. [/tex]
[tex] \left \{ {{x= \frac{143,5a}{35,5} } \atop {y= \frac{188b}{80} }} \right. [/tex]
[tex]143,5a/35,5+188b/80=100
unde a+b=39,06
rezulta ca a=4,85% Cl
b=34,21% Br[/tex]
