Cu+2AgNO3--->Cu(NO3)2+2Ag
n\(_{Cu}=\frac{8}{64}=0,125\left(mol\right)\)
n\(_{AgNO3}dư=0,01\left(mol\right)\)
m\(_{AgNO3}=0,1.170=17\left(g\right)\)
Theo pthh
n=\(2n_{Cu}=0,25\left(mol\right)\)
m\(_{Cu}=0,25.64=16\left(g\right)\)
\(n_{Cu}=0125\left(mol\right)\)
PTHH:Cu+2AgNO3-->Cu(NO3)2+2Ag
\(\Rightarrow n_{AgNO3}=0,1\left(mol\right)\Rightarrow m_{AgNO3}=17\left(g\right)\)
\(\Rightarrow m_{Cu}=0,25.64=16\left(g\right)\)
