a, \(n_{SO_2}=0,15 (mol)\)
Đặt \(n_{Ag}=x(mol)\\
n_{Cu}=y( mol)\)
\( 2Ag+2H_2SO_4\to Ag_2SO_4+2H_2O+SO_2\\
Cu+2H_2SO_4\to CuSO_4+2H_2O+SO_2\)
\(\Rightarrow\)\(\left\{{}\begin{matrix}108x+64y=17,2\\0,5X+Y=0,15\end{matrix}\right.\)
\(\Rightarrow\)\(\left\{{}\begin{matrix}X=0,1\\Y=0,1\end{matrix}\right.\)
\(m_{Ag}=0,1.108=10,8(g)\\
m_{Cu}=0,1.64=6,4(g)\)
\(\% m_{Ag}=10,8:17,2.100\%=62,79\%\\
\%m_{Cu}=100\%-62,79\%=37,21\%\)
b, \(n_{H_2SO_4}=0,3(mol)\\
m_{H_2SO_4}=0,3.98=29,4(g)\\
V=29,4:96\%:1,84=16,64ml\)
