\(\begin{array}{l}
{n_{Zn}} = \dfrac{{2,6}}{{65}} = 0,04\left( {mol} \right)\\
{n_{CuC{l_2}}} = 0,1.0,75 = 0,075\left( {mol} \right)\\
Zn\,\,\,\,\,\,\,\, + \,\,\,\,\,\,\,\,\,\,\,CuC{l_2} \to ZnC{l_2}\,\,\, + \,\,\,\,\,\,Cu\\
0,04\,mol\,\, \to \,\,0,04\,mol \to 0,04\,mol
\end{array}\)
Trong dung dịch thu được ta có:
\(\begin{array}{l}
{n_{ZnC{l_2}}} = 0,04\,mol\\
{n_{CuC{l_2}}} = 0,075 - 0,04 = 0,035\,mol
\end{array}\)
