\(n_{Zn}=\dfrac{13}{65}=0.2\left(mol\right)\)
\(n_{HCl}=\dfrac{182.5\cdot10}{100\cdot36.5}=0.5\left(mol\right)\)
\(Zn+2HCl\rightarrow ZnCl_2+H_2\)
\(0.2......0.4..........0.2........0.2\)
\(n_{HCl\left(dư\right)}=0.5-0.4=0.1\left(mol\right)\)
\(m_{HCl\left(dư\right)}=0.1\cdot36.5=3.65\left(g\right)\)
\(V_{H_2}=0.2\cdot22.4=4.48\left(l\right)\)
\(m_{\text{dung dịch sau phản ứng}}=13+182.5-0.2\cdot2=195.1\left(g\right)\)
\(C\%_{HCl\left(dư\right)}=\dfrac{3.65}{195.1}\cdot100\%=1.87\%\)
\(C\%_{ZnCl_2}=\dfrac{0.2\cdot136}{195.1}\cdot100\%=13.94\%\)
