\(m_{CuO}=30.3\cdot26.4\%=8\left(g\right)\)
\(n_{CuO}=\dfrac{8}{80}=0.1\left(mol\right)\)
\(CuO+H_2\underrightarrow{^{^{t^0}}}Cu+H_2O\)
\(0.1.................0.1.......0.1\)
\(m_{PbO}=30.3-8=22.3\left(g\right)\)
\(n_{PbO}=\dfrac{22.3}{223}=0.1\left(mol\right)\)
\(PbO+H_2\underrightarrow{^{^{t^0}}}Pb+H_2O\)

\(m_{Cu}=0.1\cdot64=6.4\left(g\right)\)
\(m_{Pb}=0.1\cdot207=20.7\left(g\right)\)
\(m_{H_2O}=0.2\cdot18=3.6\left(g\right)\)
\(V_{H_2O}=\dfrac{3.6}{1}=3.6\left(ml\right)\)
