a) Fe + CuSO4 --> FeSO4 + Cu
b) \(m_{ddCuSO_4}=100.1,12=112\left(g\right)\)
=> \(m_{CuSO_4}=\dfrac{112.10}{100}=11,2\left(g\right)\)
=> \(n_{CuSO_4}=\dfrac{11,2}{160}=0,07\left(mol\right)\)
\(n_{Fe}=\dfrac{1,96}{56}=0,035\left(mol\right)\)
PTHH: Fe + CuSO4 --> FeSO4 + Cu
____0,035->0,035----->0,035
=> \(\left\{{}\begin{matrix}C_{M\left(CuSO_4\right)}=\dfrac{0,07-0,035}{0,1}=0,35M\\C_{M\left(FeSO_4\right)}=\dfrac{0,035}{0,1}=0,35M\end{matrix}\right.\)
