\(n_{Zn}=\dfrac{16.25}{65}=0.25\left(mol\right)\)
\(n_{Cl_2}=\dfrac{3.36}{22.4}=0.15\left(mol\right)\)
\(Zn+Cl_2\underrightarrow{^{t^0}}ZnCl_2\)
\(0.15...0.15.....0.15\)
\(Zn+2AgNO_3\rightarrow Zn\left(NO_3\right)_2+2Ag\)
\(0.25-0.15..................................0.2\)
\(ZnCl_2+2AgNO_3\rightarrow Zn\left(NO_3\right)_2+2AgCl\)
\(0.15..................................................0.3\)
\(m_{AgCl}=0.3\cdot143.5=43.05\left(g\right)\)
\(m_{Ag}=0.2\cdot108=21.6\left(g\right)\)
\(m\downarrow=43.05+21.6=64.65\left(\right)\)
